The surface area of a cube is 150 cm2. Its volume is :
A. 64 $${\text{c}}{{\text{m}}^3}$$
B. 125 $${\text{c}}{{\text{m}}^3}$$
C. 150 $${\text{c}}{{\text{m}}^3}$$
D. 216 $${\text{c}}{{\text{m}}^3}$$
Answer: Option B
Solution (By Examveda Team)
$$\eqalign{ & 6{a^2} = 150 \cr & \Rightarrow {a^2} = 25 \cr & \Rightarrow a = 5 \cr} $$∴ Volume :
$${a^3} = {5^3} = 125\,{\text{ c}}{{\text{m}}^3}$$
