Question

how many bricks each 25cm long,10cm wide and 7.5cm thick,will be required for a wall 15 m long ,2.5 m high and 1.25 m thick?

Answer 1

hey

I am meritkshitij here.



at first,we will find volume of wall=l × b × h



=15 × 2.5 × 1.25. m³



now,let us find volume of a brick



=0.25 × 0.1 × 0.75. m³ ( converted in metre)



now, no. of bricks



= volume of wall/ volume of a brick



=15×2.5×1.25/0.25×0.1×0.75



=2500 bricks Ans.



Thanks.

Answer 2

Volume of bricks = 25*10*7.5 centimetre cube
Volume of waal = 15*2.5*1.25 metere cube = 1500*250*125 centimetere cube
No of bricks = volume of waal / VOlume of bricks
So...... 1500*250*125/25*10*7.5
=. 1500*10*125/75
=. 500*10*5
=. 25000 bricks are required


Hope the answer is correct and would help u.. .!!!!!!!!
