Question

I WILL MEDAL!!

Answer 1

The prism has a surface area of 1312 mm2.

What would the surface area of the prism be if each dimension were halved?

Answer 2

So each dimention is 32 by 8 by 10
so the surface area=2 times(8 times 10)+(2 times (32 times 10))+(2 times (8 times 32))=2 times 80+2 times 320+2 times 256=1312

if halved
just divide each by 2
(2 times 4 times 5)+(2 times 16 times 5)+(2 times 4 times 16)=(2 times 20)+(2 times 80)+(2 times 64)=40+160+128=328
the new surface area is 328 mm^2

Answer 3

or just divide by 4
1312/4=328
you are halving each side and each of the 6 sides and thus quartered so the final answer is quartered also
