Find, volume of a cube of side a = 1.4 x...

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

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
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)`.
