Question

find the volume of cube​

Answer 1

Solution -

• We have two cubes with different dimensions and need to find their volumes.

For finding volume of a cube, we use

$\large{\bf{\longmapsto{\boxed{\pink{Volume_{(Cube)} = a^3}}}}}$

⠀

⠀⠀(a) a = 3.5 cm

$\tt\dashrightarrow{Volume = a^3}$

$\tt\dashrightarrow{Volume = (3.5)^3}$

$\bf\dashrightarrow{Volume = 42.875\: cm^3}$

⠀

⠀⠀(b) a = 5 m

$\tt\dashrightarrow{Volume = a^3}$

$\tt\dashrightarrow{Volume = (5)^3}$

$\bf\dashrightarrow{Volume = 125\: m^3}$

Answer 2

Concept:-

Here we have given that the sides of the cube is 3.5 cm and 5 m so to find out the volume of the cube we will use the formula.

                   ____________

Question 1:-

• ➝ Volume = a³

• ➝ Volume = ( 3.5 )³

• ➝ Volume = 3.5 × 3.5 × 3.5

• ➝ Volume = 42.875 cm³

. ° . The volume of the cube is 42.875 cm³

                        ____________

Question 2:-

• ➝ Volume = a³

• ➝ Volume = ( 5 )³

• ➝ Volume = 5 × 5 × 5

• ➝ Volume = 125 m³

. ° . The volume of the cube is 125 m³
