Question

A closed box has a square base with side length l feet and height h feet. Given that the volume of the box is 17 cubic feet, express the surface area of the box in terms of l only.

Answer 1

V = 17 ft^3 = hL^2

h = 17/L^2

Surface Area of the box = 2L^2 + 4Lh = 2L^2 +4L(17/L^2) = 2L^2 +68/L

SA = 2L^2 +68L

for example, a box 17 by 1 by 1 has V = 17

SA = 2+68 = 70 = 4(17x1) + 2(1x1) = 68+2 = 70 ft^2
