Question 13. The volume of a cube in m³ is equal to the surface area of the cube in m². The volume of the cube is (a) 64 m³ (b) 216 m³ (c) 512 m³ (d) 196 m³ Answer
Correct option is B) Let the side length of the cube be l. Volume of the cube V=l 3 Surface area of the cube S=6l 2 But, V=S (Given) Or l 3 =6l 2 ⟹ l=6 m Thus, volume of the cube V=l 3 =6 3 m 3 =216 m 3
