Question

Find the volume of the cube whose side is 2.5 meters ​

Answer 1

Answer:

$\bigstar{\bold{Volume\:=\:15.625\:m^{3}}}$

Step-by-step explanation:

$\Large{\underline{\underline{\bf{Given:}}}}$

• Side of cube = 2.5 m

$\Large{\underline{\underline{\bf{To\:Find:}}}}$

• Volume of the cube

$\Large{\underline{\underline{\bf{Solution:}}}}$

→ Volume of a cube is given by

  Volume of cube = a³

  where a is a side of the cube.

→ Substituting the given data we get,

  Volume = (2.5)³

  Volume = 2.5 × 2.5 × 2.5

$\boxed{\bold{Volume\:=\:15.625\:m^{3} }}$

$\Large{\underline{\underline{\bf{Solution:}}}}$

→ Total surface area of a cube = 6a²

→ Volume of a cube = a³

→ Diagonal of a cube = √3 a

Answer 2

Given ,

The side of cube (a) = 2.5 m

We know that , the volume of cube is given by

$\boxed{ \sf{Volume = {(a)}^{3} }}$

Thus ,

Volume = (2.5)³

Volume = 2.5 × 2.5 × 2.5

Volume = 15.625 m³

Therefore ,

The volume of cube is 15.625 m³
