Question

find the volume of a cube whose edge is 2.5m

Answer 1

Answer:

volume of cube=a^3

=2.5^3

=15.625cm^3

Answer 2

Answer:

The volume of the cube is 15.625$m^{3}$

Step-by-step explanation:

We have been given here to find the volume of the following cube whose edge is 2.5 m Now as we know that a cube has all the sides equal and so the formula of the volume of the cube is as below:

Volume = $(side)^{3}$

Side = 2.5m

∴ Volume = $(2.5)^{3}$

= 2.5 × 2.5 × 2.5 $m^{3}$

= $\frac{25}{10}$ × $\frac{25}{10}$ × $\frac{25}{10}$$m^{3}$

= $\frac{5}{2}$ × $\frac{5}{2}$ × $\frac{5}{2}$  $m^{3}$

= $\frac{125}{8} m^{3}$

= 15.625 $m^{3}$

The volume of cube 15.625 $m^{3}$
