The CAT Online Free Test Prep MCQs Geometry - Three Dimensional Figures

A | B | C | D | E |

Let e be the length of an edge of the cube. Recall that the volume of a cube is e^{3} and its surface area is 6e^{2}. Since we are given that both the volume and the surface area are x, these expressions are equal:
