MCQ
A cube has numerically equal volume and surface area. The volume of such a cube is ........... $units$
- ✓$216 $
- B$1000$
- C$2000$
- D$3000$
✓
Answer
Correct option: A.
$216 $
a
(a) Volume of cube = ${a^3}$
(a) Volume of cube = ${a^3}$
Surface area of cube = $6{a^2}$
according to problem $a^3 = 6a^2 $ $⇒$ $ a = 6$
$V = {a^3} = 216\,units$.
