Question

Which is the side length of a cube with a surface-area-to-volume ratio of faction 1/2

Answer 1

12

Explanation:

For a cube of side length, L

The following formulas apply:

Area = 6L²

Volume = L³

Area / Volume = 6L² ÷ L³ = 6/L

Try L = 12

Area / Volume = 6/12 = 1/2

Hence 12 is the answer.
