Question

5. If one side of a cube is 15cm. Find its volume

Answer 1

if one side of the cube is 15 cm then it's volume will be
S3. 15*15*15=3375cm3

Answer 2

Given,

One of the sides of a cube is 15cm.

That is, a = 15 cm.

To find out,

The volume of cube.

Solution:

$\huge \: volume \: of \: cube \: = {side}^{3} = {a}^{3} \\ \\ volume \: = {15}^{3} \\ \\ volume \: = 15 \times 15 \times 15 \\ \\ volume \: = 3375 \: {cm}^{3}$

Therefore the volume of a cube whose side is 15 cm is 3375 cm^3.

Proof:

$\huge \: volume \: of \: cube \: = {a}^{3} \\ \\ 3375 = {15}^{3} \\ \\ 3375 = 15 \times 15 \times 15 \\ \\ 3375 = 3375$

Additional information:

$\huge \: curved \: surface \: area \: of \: cube \: = 4 {a}^{2}$

$\huge \: total \: surface \: area \: of \: cube \: = 6 {a}^{2}$

$\huge \: volume \: of \: cube \: = {a}^{3}$
