Question

Find the number of bricks each measuring 20 cm × 15 cm× 6 cm required to construct a wall 5 m long 4.5 m high and 0.6 m thick .​

Answer 1

Answer:

7500

Step-by-step explanation:

volume of wall = l*b*h

= 5*4.5*0.6

= 13.5m3

volume of 1 brick= 0.2*0.15*0.06

= 0.0018m3

number of bricks=13.5/0.0018

=7500
