Find, volume of a cube of side a = `1.4 xx (10^-2)` m.

Answer

A, B, C

Explanation

Volume `V=a^3`
`=(1.4 xx 10^(-2)) xx (1.4 xx 10^(-2)) xx (1.4 xx 10^(-2)) = 2.744 xx 10^(-6) m^(3)`
Since, each value of `a` has two significant figures. Hence, we will round off the result to two significant figures.
`V = 2.7 xx 10^(-6) m^(3)`.
