MCQ - 47-11899

Question:

The volume of a cube is x and its surface area is x. What is the length of an edge of the cube?

Correct Answer: A

Explanation:

Let e be the length of an edge of the cube. Recall that the volume of a cube is e³ and its surface area is 6e². Since we are given that both the volume and the surface area are x, these expressions are equal:

We reject e = 0 since in that case no cube would exist. Hence, e = 6 and the answer is (A).
