Question

A cube has a surface area of 200 square inches. Which choice is closest to the length of an edge of the cube?

Answer 1

It would be more helpful to know your choices, but since a cube has 6 sides,

200 ÷ 6 = 33 1/3

33 1/3 is the area of each side

Lengths of each side are the same, so square root of 33 1/3 is about 5.77 inches. Pick whichever is closest to that.

Answer 2

5.8 according to your ttm.
