Question

a brick has length 23cm breadth 11cm and height 8 cm.how many such bricks will be required to build a 92 m long 4m high and 26.4 cm thick wall?

Answer 1

Answer:

480

Step-by-step explanation:

Let x be the number of bricks needed.

Volume of 1 brick * x = volume of wall

Volume of 1 brick (cuboid)= lbh= 23*11*8= 2024 cm^3

Volume of wall=LBH= 92*400*26.4cm^3

Therefore, x= (92*400*26.4)/2024 = 480

Hence the number of bricks required is 480.
