Question

2. If the perimeter of one face of a cube is 40 cm, then its volume is
(a) 64000 cm3 (b) 1000 cm3 (c) 240 cm (d) 64 cm​

Answer 1

( b. ) 1000 cm³

Step-by-step explanation

Given:

The perimeter of one face of a cube is 40 cm.

To find out:

Find the volume of given cube ?

Formula used:

• Perimeter of cube = 4 × side

• Volume of cube = ( side ) ³

Solution:

We know that,

Perimeter of cube = 4 × side

→ 40 = 4 × side

→ Side = 40/4

→ Side = 10 cm

Now,

⋆ Volume of cube = ( Side )³

= ( 10 )³

= 1000 cm³

Hence, the volume of given cube is 1000 cm³.

Answer 2

Answer:

(b) 1000cm³

Given:

the perimeter of one face of a cube is 40cm.

To find out:

find the value of given cube?

formula used:

perimeter of cube = 4 × side

volume of cube = (side)³

Solutions:

We know that

perimeter of cube = 4 × side

40 = 4 × side

side = 40/4

side = 10cm

Now,

Volume of cube = (side)³

(10)³

1000cm³

hence, the volume of given cube is 1000 cm³.
