The surface area of a cube is 150 cm2. Its volume is :
Answer & Solution
Correct Answer:
Option
B
$$\eqalign{
& 6{a^2} = 150 \cr
& \Rightarrow {a^2} = 25 \cr
& \Rightarrow a = 5 \cr} $$
∴ Volume :
$${a^3} = {5^3} = 125\,{\text{ c}}{{\text{m}}^3}$$
∴ Volume :
$${a^3} = {5^3} = 125\,{\text{ c}}{{\text{m}}^3}$$
