Question

What is the volume of a cube whose side is 10 cm?

Answer 1

the first one Is right answer

Answer 2

Answer: The volume of the cube is $10^{-3}m^3$

Explanation:

To calculate the volume of cube, we use the formula:

$V=a^3$

where,

a = edge length of cube = 10 cm = 0.1 m     (Conversion factor: 1 m = 100 cm)

Putting values in above equation, we get:

$V=(0.1)^3=0.001m^3=10^{-3}m^3$

Hence, the volume of the cube is $10^{-3}m^3$
