The Absolute Best Book to Challenge Your Smart Student!

The correct answer is 24.
A cube has 12 edges. The formula for the volume and surface area of a cube are:
V = S\(^3\) SA = 6S\(^2\)
The volume of a cube is one-third of the total surface area of the cube. Thus:
S\(^3= \frac{1}{3}\)6S\(^2\)
Remove S\(^2\) from both sides and solve for S.
S = \(\frac{1}{3}\)6 = 2
One side of the cube is 2. The sum of all edges is
2 × 12 = 24
