Correct Answer: C

The total surface area of a cube is the sum of the areas of all surfaces. A cube has six surfaces: 600 ÷ 6 = 100. Each surface of the cube, which is a square, has an area of 100. That means each edge is 10 because the area of a square is side × side. The volume of a cube is edge3. In this case, that’s 10 × 10 × 10 = 1,000. Correct Answer: C.
