Question

A cube has a side of length 1.2 x 10^-2 m. Calculate its volume
(1) 1.7 x 10^-6 m3
(2) 1.73 x 10^-6 m3
(3) 1.70 x 10^-6 m3
(4) 1.732 x 10^-6 m3​

Answer 1

Answer:

Explanation:

Here

Length of the cube, L=12x10  

−2

m

Volume of the cube, V=(1.2×10  

−2

m)  

3

=1.728×10  

−6

m  

3

 

As the result can have only two significant figures, therefore, on rounding off, we get, V.1.7×10  

−6

m
