how many brick of length 25 CM, breadth 15 CM and height 10 CM are required to build a wall of length 6m height 2.5m and breadth 0.5 m
Answers
length of brick =25cm
breadth=15 cm
height= 10cm
length of wall=6m...1m=100cm,,
=600cm
breadth= 25×100÷10
=250cm
height=5×100÷10
= 50cm
volume of brick=l×b×h
=25×15×10
=3750
volume of wall
=600×250×50
=7500000
to find ...
volume of wall ÷ volume of brick
7500000÷3750
=2000
2000cm are the brick required to build a wall
Answer:
Given, a cuboidal shape brick having dimensions:
length (l1) = 25 cm,
breadth (b1) = 15 cm,
height (h1) = 10 cm
And, a cuboidal shape wall:
length (l2) = 6 m,
height (h2) = 2.5 m,
breadth (b2) = 0.5 m
Required to find: Number of bricks required to build the wall
From the question it’s understood that,
When all the bricks are arranged to build a wall, the volume of all the bricks is equal to volume of wall.
So,
Number of bricks = Volume of the wall/ Volume of a brick
Now,
Volume of a brick = l1 x b1 x h1
= 25 x 15 x 10 cc
And, we have
l2 = 6m = 6 x 100 [∵ 1m = 100cm]
= 600 cm
h2 = 2.5 m = 2.5 x 100 = 250 cm
b2 = 0.5 m = 0.5 x 100 = 50 cm
So,
Volume of the wall = l2 x b2 x h2
= 600 x 50 x 250 cc
Finally, the Number of bricks = Volume of the wall/ Volume of a brick
= (600 × 50 × 250)/ (25 × 15 × 10)
= 40 x 2 x 25
= 2000 bricks
Therefore, the number of bricks required to build the wall is 2000.
