How many bricks will be required to build a wall 4.5 CM long 22.5 CM wide and 3 metre high if the size of a brake is 22.5 CM multiply 10 cm multiply 7.5 centimetre
Answers
Answer:
18 Brick is required to build the wall
Step-by-step explanation:
wall
length=4.5.cm breath=22.5cm height=3m
1m=100cm
=300cm
brick
length=22.5cm. breath=10cm. height 7.5cm
volume of wall=4.5x22.5x300
=45x225x3
=45x675
=30375cm^2
volume of Brick=22.5x10x7.5
=225x7.5
=1687.5cm^2
Number of Brick required to build the wall=30375
÷1687.5
