Did I do this right?
SA= 2(3 ½ + 11 ½ ) + 2(11 ½ + 11 ¾ ) + 2(3 ½ + 11 ¾ )
SA = 2(30) + 2(46.5) + 2(30.5)
SA= 60 + 93 + 61
SA= 214

Best ResponseYou've already chosen the best response.0It looks like you already multiplied everything by two in the second step and put it in parenthesis. So, the additional 2 outside would not be needed at this point.

Best ResponseYou've already chosen the best response.0SA = 2(15) + 2(23.25) + 2(15.25) should be what you have in step 2.

Best ResponseYou've already chosen the best response.0Basically step 2 should be SA = 2(15) + 2(23.25) + 2(15.25).

Best ResponseYou've already chosen the best response.0So all i have to do is do SA = 2(15) + 2(23.25) + 2(15.25) and get my answer?

Best ResponseYou've already chosen the best response.0It looked like you accidentally multiplied by 2 going to that step and didn't realize it. Otherwise it would be (30) + (46.5) + (30.5). But that would require two steps.

Best ResponseYou've already chosen the best response.0ok let me see what i get

anonymous

Best ResponseYou've already chosen the best response.0That is correct. Also there is another way you could have done it which would give the same answer. Since everything is multiplied by 2, you can separate it and add everything else together.

Best ResponseYou've already chosen the best response.0SA= 2(3 ½ + 11 ½ ) + 2(11 ½ + 11 ¾ ) + 2(3 ½ + 11 ¾ ) SA = 2(3 ½ + 11 ½ + 11 ½ + 11 ¾ + 3 ½ + 11 ¾ ) SA= 2(53 ½) SA= 107

Best ResponseYou've already chosen the best response.04. What is the surface area of the box if it is scaled up by a factor of 10? its with the same question i asked before

anonymous

Best ResponseYou've already chosen the best response.0I dont know what it wants me to do

anonymous

Best ResponseYou've already chosen the best response.0Scaling something by a factor essentially means multiplying everything in the equation by that factor.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Since your factor is 10, you would simply multiply the Surface Area you already have by that factor (10).

Best ResponseYou've already chosen the best response.0Out of curiosity, what was the original question that brought you to your work that you originally asked about?

anonymous

Best ResponseYou've already chosen the best response.01. List the dimensions of your box. Be sure to include the units (in, cm, ft., etc.). 2. Describe the shape of the cross section when the box is cut parallel to the base. 3. What is the surface area of the box? 4. What is the surface area of the box if it is scaled up by a factor of 10? 5. What is the volume of the box? 6. What is the volume of the box if it is scaled down by a factor of ½?

Best ResponseYou've already chosen the best response.0OK, we need to back up to your original question as you set up the formula wrong.

anonymous

Best ResponseYou've already chosen the best response.0hehe, it happens. Did you have to pick an item to measure or was dimensions already give to you?

Best ResponseYou've already chosen the best response.0The formula for SA is 2 ( lw + lh + hw) or 2(lw) + 2(lh) + 2(hw) where the letters besides each other mean to multiply, not add.

Best ResponseYou've already chosen the best response.0Sorry, I didn't think about your equation when you asked, was just making sure the math was correct.

anonymous

Best ResponseYou've already chosen the best response.0So, you would be multiply fractions by using those measurements.

anonymous

Best ResponseYou've already chosen the best response.0Would you like to try something different or keep with the binder?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0um i already have the measurements so keep it lol

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Ok, so now you would have SA= 2(3 ½ * 11 ½ ) + 2(11 ½ * 11 ¾ ) + 2(3 ½ * 11 ¾ )

anonymous

Best ResponseYou've already chosen the best response.0SA= 2(3 ½ * 11 ½ ) + 2(11 ½ * 11 ¾ ) + 2(3 ½ * 11 ¾ ) SA= 2(40.25 ) + 2(135.125 ) + 2(41.125 )

anonymous

Best ResponseYou've already chosen the best response.0sorry, this place is annoying with fractions. .125 would be 1/8

Best ResponseYou've already chosen the best response.0Now, since we are dealing with multiplying in our original equation instead of adding it changes the factor question somewhat.

anonymous

Best ResponseYou've already chosen the best response.0how would it be different?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0It is like saying SA = 2(10l * 10w) + 2(10l * 10h) + 2(10w * 10h)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0essentially you are multiplying all of your measurements by 10 and changing the equation to those new measurements.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Since what really changes is you add are now multiplying by 10 * 10. So instead of 10 you would multiply your final answer by 100 instead. This part is simply a shortcut and if you are required to show your work you may have to multiply each measurement by 10 and redo the work.

Best ResponseYou've already chosen the best response.0SA= 2(35 + 115 ) + 2(115 + 117.5 ) + 2(35 + 117.5 )

anonymous

Best ResponseYou've already chosen the best response.0This would be your new formula if you multiplied each side by 10.

Best ResponseYou've already chosen the best response.0oops, i made a mistake on that last formula, ignore it.

Best ResponseYou've already chosen the best response.0The biggest thing in math is to learn your formulas. As long as you start with the right formula, chances are you will do really well.

anonymous

Best ResponseYou've already chosen the best response.0There are so many though.

anonymous

Best ResponseYou've already chosen the best response.0I memorize most of them but i have trouble with long ones

anonymous

Best ResponseYou've already chosen the best response.0Usually math teachers will give you a sheet with the formulas when you take tests so it is generally ok to use one when doing homework.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Don't worry, I think we all have that problem. Trying to remember all of the formulas can be tough. It doesn't hurt to try and set up your work from memory but before you actually start doing it, go back and make sure you had the formula right.

Best ResponseYou've already chosen the best response.0The volume of a rectangular prism is V=bh right? i think im wrongl ol

anonymous

Best ResponseYou've already chosen the best response.0Also, I find it helpful to right down the formula before starting the work.

anonymous

Best ResponseYou've already chosen the best response.0Volume is in three dimensions so you would have a third measurement there. V = lhw

anonymous

Best ResponseYou've already chosen the best response.0oh ok so it would be.... V= 11 3/4 x 11 1/2 x 3 1/2

anonymous

Best ResponseYou've already chosen the best response.0LOL, see why i asked if you wanted to measure something else. :) Ask your teacher if it is okay to round up for future reference that way you aren't haven't to spend so much time on one problem.

Best ResponseYou've already chosen the best response.0Ok, what do you think it means to scale the box down by 1/2?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Subtract by 1/2 i guess?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Not quite. like I said before, a factor is a number you multiply by. So, you would multiply each of your sides by 1/2. Or, in other words, half of your original measurements.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so half of 3.5, half of 11.5, and half of 11.75

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ok that would beeee....

anonymous

Best ResponseYou've already chosen the best response.0Hope you are ok with me doing decimals, should have asked I know your original measurements are in fractions. That doesn't confuse you, does it?

anonymous

Best ResponseYou've already chosen the best response.0That is very close to exact. If I was you, I would just round that to 59. Also, you could probably round the last answer to 473.

anonymous
