Question

A cube has numerically equal volume and surface area. The volume of such a cube is

• A. 216 units
• B. 1000 units
• C. 2000 units
• D. 3000 units

Answer 1

Answer: (A)

216 units

Answer 2

Volume of cube = $a^{3}$

Surface area of cube = $6a^{2}$

according to problem a³ = 6a² ⇒ a = 6

∴$V = a^{3} = 216units$.
