find the numbers of bricks required to build wall of length 5m , breadth 4m, and height 25cm and bricks length is 20m, breadth 10m and the height is 6.25 m. calculate the number of bricks.
Answers
Answer : 4000 bricks.
Step-by-step explanation:
Firstly:- The dimensions of bricks should be in cms.
If it's cm then answer is-
Volume if brick:- l×b×h = 20×10×6.25 cm^3
= 1250 cm^3
Now, Volume of Wall :- (In cms)
=500×400×25
= 5000000 cm^3
No. of bricks required:- 5000000÷ 1250
= 4000.
Answer:
h of wall=25cm
b " " "=4m
l " " "=5m
l of bricks =20m
b=10m
h=6.25m
volume of wall =2( lb×bh×hl)
convert cm into m= 25/100=4m
2×4×5×5×25×25×5 = 625000
= 625000 cm
volume of wall = 80 cm 2
volume of one brick = l×b×h
20×10×6.25= 1250
no of bricks = volume of wall × volume of bricks
625000× 1250= 781250000answer
