Question

To construct a wall 24 m long, 0.4 m thick , 6 m high , bricks of dimensions 25 cm × 16 cm × 10 cm, each are used .if the mortar occupies 1\10 th of the volume of the wall, find the number of the bricks used ?

Answer 1

Answer:

12960 bricks

Step-by-step explanation:

Volume of 1 brick = 25*16*10 cm^3 = 4000cm^3

Volume of the wall = 24*0.4*6 = 57.6 m^3

1/10th by mortar i.e. 5.76 m^3

Volume covered by bricks= 51.84 m^3

So, the number of Bricks required =( 51.84/4*1000) m^3 , which is 12960.
