Question

Find the volume of each of the cube whose sides are
(i) 6.4cm
(ii) 1.3 m
(iii) 1.6 m

Answer 1

We have the volume of cube, $V=a^3$, where, $a$ is the side.

(i) $a=6.4cm$

$V=a^3=(6.4{)}^3=262.144c{m}^3$

(ii) $a=1.3m$

$V=a^3=(1.3{)}^3=2.197m^3$

(iii) $a=1.6m$

$V=a^3=(1.6{)}^3=4.096m^3$
