Question

how many bricks 20cm×25cm willbe required to pave the hoor 6m×5m? ​

Answer 1

$\huge\mathfrak\green{Solution}$

Volume of the wall =l * b * h

• Given that

l=24m

b=6m

h=0.4m

Volume=24*6*0.4=57.6m^3

Volume of 1 brick =.25m*.16m*.10m

=.004m^3

• Bricks need to build a wall =volume of wall/volume oh bricks

57.6/.004=14400m^3

so the walls needed = 14400m^3

Answer 2

$600 cm \times 500cm = n \times 20cm \times 25cm$

$n = 600 \times 500 \div 20 \times 25 \\ n = 300000 \div 500 \\ n = 600$

$\boxed{n=600}$
