EXPLANATION.
- GIVEN
Dimensions of bricks = 15 cm X 25 cm X 7 cm.
Dimension of wall = 10 m X 1.5 m X 14 m.
According to the question,
Volume of a wall = 10 X 1.5 X 14 = 210 m^3
210000000 cm^3
Volume of a bricks = 15 X 25 X 7 = 2625 cm^3
No of bricks = 210000000 / 2625
=> 80000 = Answer
Some related formula.
1) = volume of cuboid = L X B X H
2) = volume of cube = a^3
3) = volume of cylinder = πr^2h
4) = volume of cone = 1/3 πr^2h
5) = volume of sphere = 4/3 πr^3
6) = volume of hemisphere = 2/3 πr^3
