Question

Julia is wrapping a block of cheese shaped like the prism shown in shrink wrap. What is the minimum amount of shrink wrap that she will need?

Answer 1

Answer: C. 41.2in

Explanation:

Let L be length, W be width, H be height, and P be hypotenuse.

L = 4 in

W = 3 in

H = 2.2 in

P = 4.6 in

Area = LW + LH + WH + PW

= 4(3) + 4(2.2) + 3(2.2) + 4.6(3)

= 12 + 8.8 + 6.6 + 13.8

= 41.2

Thus, Julia will need at least 41.2in^2 of shrink wrap.
