Best ResponseYou've already chosen the best response.0Find the area of each side and add together... that's surface area I'm having a brain fart haha What is it you want to find?

Best ResponseYou've already chosen the best response.0perimeter of the base times height of the prism + 2Base = Total Area

Best ResponseYou've already chosen the best response.0Area of Triangle : 1/2 times 9 "correct" ?

Best ResponseYou've already chosen the best response.01/2 time base of the triangle times the height of the triangle. Because you are only given the base, you need to find the height.

Best ResponseYou've already chosen the best response.0And to find the height we use pythag theorem correct?

Best ResponseYou've already chosen the best response.0So your new base would be 1.5 and the hypo would still be 3, yep

Best ResponseYou've already chosen the best response.0So the height would be a^2?

anonymous

Best ResponseYou've already chosen the best response.0c= 3, b=1.5, and yep a= a

Best ResponseYou've already chosen the best response.0so when you plug into pythag, you would get that

Best ResponseYou've already chosen the best response.0So i find the area of the triangle and multiply it by 2 Then i add ?

anonymous

Best ResponseYou've already chosen the best response.0add that to the (perimeter of the base x height), which would be (3+3+3)(6)

Best ResponseYou've already chosen the best response.0Area of Triangle = 1.5√6.75 correct?

phi

Best ResponseYou've already chosen the best response.0btw, people would write \[\sqrt{6.75} \] as \[ \frac{3 \sqrt{3}}{2}\]

Best ResponseYou've already chosen the best response.0Okay i got it. Thanks so much!! I just needed a refresh it's been awhile :)

Best ResponseYou've already chosen the best response.0So it would be 4.5√3 / 2 @phi ?

phi

Best ResponseYou've already chosen the best response.0generally you don't mix decimals and fractions i.e. 4.5/2 If you have a multiple choice you probably would see the answer as a pure fraction \[ \frac{4}{9}\sqrt{3} \]

phi

Best ResponseYou've already chosen the best response.0double that for the other triangle now you have 3 faces that all look the same size 3x6 3 faces each 18 = 54 plus the two triangles 8/9 sqrt(3)

phi

Best ResponseYou've already chosen the best response.0you have two triangles (the ends) and 3 "side faces" right?
