(d) If the height of 1 brick is 12 cm, then how many bricks are required to make a pillar of 108 cm?
Answers
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.
