Answer 1

hey mate here is your answer
volume of brick= 20×10×6=1200cm^3
change in cm
lenght of wall=6000cm
breadth of wall=25cm
height of wall=200cm
volume of wall=6000×25×200= 3000000cm^3
no. of bricks required=volume of wall÷volume of a brick= 3000000÷1200=2500 bricks..
plzz mark me brainliest.

Answer 2

Answer:

25000 bricks

Step-by-step explanation:

$brick \\ l = 20cm \\ b = 10cm \\ h = 6cm \\ wall \\ l = 6000cm \\ b = 25cm \\ h = 200cm \\ no.of \: bricks \: required = \frac{vol.of \: wall}{vol.of \: brick } \\ = \frac{lbh}{lbh} = \frac{6000 \times 25 \times 200}{20 \times 10 \times 6} \\ = 25 \times 1000 \\ = 25000$
