Best ResponseYou've already chosen the best response.0each square is 5. find the surface area, ive been doing this for 3 hours, on this type of stuff.

Best ResponseYou've already chosen the best response.0OK you gotta have to count squares. But you got to do it in smart way. OK clearly this is 3D. But imagine looking it at certain angle (front, top, and side), so it would looks like 2D Then there will be SAME number of square on opposite sides of whatever you are "looking" at. Get the plan?

Best ResponseYou've already chosen the best response.0For example, if you are looking at top, you will kind of see this: dw:1433950339164:dw

Best ResponseYou've already chosen the best response.0then multiply that by 2, for other side (bottom)

Best ResponseYou've already chosen the best response.0which would be 16?

Best ResponseYou've already chosen the best response.0Yes there are 16 squares for TOP and BOTTOM. Now count front.

Best ResponseYou've already chosen the best response.0you would see this:dw:1433950434314:dw

Best ResponseYou've already chosen the best response.0yeah 16. so double that for other sides and you have 32

Best ResponseYou've already chosen the best response.0OK now double that. 24

geerky42

Best ResponseYou've already chosen the best response.0Now add them all together: 24 + 32 + 16 = ?

Best ResponseYou've already chosen the best response.0Yep. So there are 72 squares. Now for each square, what is area?

geerky42

Best ResponseYou've already chosen the best response.0No. multiply 5 by 5. What do you get?

Best ResponseYou've already chosen the best response.0im a very slow learner, sorry :(

Best ResponseYou've already chosen the best response.0To get area, you just multiply length by width, right?

geerky42

Best ResponseYou've already chosen the best response.0OK, so length of square is 5 and width is also 5

geerky42

Best ResponseYou've already chosen the best response.0So you have \(Area = 5\times5\)

Hayleymeyer

Best ResponseYou've already chosen the best response.0okay, which would be 25

geerky42

Best ResponseYou've already chosen the best response.0Yeah Area of EACH square is 25. And there are 72 squares. So multiply 72 by 25. That would be your surface area.

Best ResponseYou've already chosen the best response.0my bad, I don't no why my calculator is messing up

Best ResponseYou've already chosen the best response.0OK, so you got 1800, right? So your surfacce area is\[SA = \boxed{1800~\text{mm}^2}\]

Best ResponseYou've already chosen the best response.0Just got to count the smart way, kinda.
