Question

What is the volume of a cube (in cu cm) if the area of its base is 64 sq cm?

• A. 128
• B. 256
• C. 512
• D. 768

Answer 1

The correct option is C 512

The base area of the cube = 64 sq cm
We know, base area = Side $\times$ Side
So, Side $\times$ Side = 64 sq cm
8 $\times$ 8 = 64
$\therefore$ Side = 8 cm

Volume of the cube
= Side $\times$ Side $\times$ Side

So, Volume of the given cube
= 8 $\times$ 8 $\times$ 8 = 512 cu cm
