Question

Total surface area of a cube is 216 cm². Hence, its volume is ________cm³ (a) 36
(b) 216
(c) 12
(d) 6

Answer 1

The answer is (b)216
Surface area of cube=6a^2
(a=side of square)
Given: S.A.=216cm^2
Therefore, 216cm^2=6a^2
216cm^2/6=a^2
36cm^2=a^2
√36cm^=a
6cm=a
Now, Volume=a^3
Volume=6cm^3=216cm^3
