Question

the volume of a cube is 8000cm cube. find the edge of the cube.

Answer 1

volume of the cube=8000cm cube.
therefore, side c

Answer 2

The edge of the cube = 20 cm

Given :

The volume of a cube is 8000 cm³

To find :

The edge of the cube

Formula :

Volume of a cube = Side³

Solution :

Step 1 of 2 :

Form the equation to find edge of the cube

Let edge of the cube = x cm

Then volume of a cube = x³ cm³

By the given condition

$\sf {x}^{3} = 8000$

Step 2 of 2 :

Find edge of the cube

$\displaystyle \sf{ {x}^{3} = 8000}$

$\displaystyle \sf{ \implies {x}^{3} = {20}^{3} }$

$\displaystyle \sf{ \implies x = 20 }$

The edge of the cube = 20 cm
