Step-by-step explanation:

Length of brick=25cm

breadth of brick =15cm

height of brick=10cm

volume of brick =length×breadth×height

=25cm×15cm×10cm

=3750cm

3

length of wall=6m=600cm

breadth of wall=0.5m=50cm

height of wall =2.5m=250cm

volume of wall=length×breadth×height

=600×250×50=7500000cm

3

the number of bricks required=

3750

7500000

=

375

750000

=2000

hence, number of bricks =2000

No. of bricks required to make the pillar = 9 bricks

Given,

Height of one brick, h = 12 cm

Height of the pillar, H = 108 cm

To Find,

No. of bricks required to build the pillar, n

Solution,

This problem could be solved using a very simple method.

We have been given a scenario of making a pillar having a height of 108 cm.

For this, we use bricks, each having a height of 12 cm.

Our objective is to find out the number of such kind of bricks required in building the pillar.

Let the no. of bricks used for making the pillar be n.

Then, we can deduce the a mathematical relationship with the height of the pillar (H) and the height of a brick (h).

⇒ H = h × n

⇒ 108 = 12 × n

⇒ n = 108 ÷ 12

⇒ n = 9

Therefore, 9 bricks are required in building the pillar.
