8. A rectangular wall is 27 m long, 60 cm thick and 4 m high. If cube-shaped
bricks of side 30 cm each are used, how many bricks will be required to build
the wall?
Answers
Answer:
A rectangular wall is 27 m long, 60 cm thick and 4 m high. As we know 1 m = 100 cm, so convert all the measurement in cm. Cube-shaped bricks of side 30 cm each are used. Hence, the number of bricks will be required to be the wall is 2400

Answer:
The number of bricks will be required to be the wall is 2400.
Step-by-step explanation:
Consider the provided information.
Volume of cuboid = length × breadth × height
A rectangular wall is 27 m long, 60 cm thick and 4 m high.
As we know 1 m = 100 cm, so convert all the measurement in cm.
Volume of the wall = 27 m × 60 cm × 4 m
= 27 × 100 cm × 60 cm × 4 × 100 cm
Cube-shaped bricks of side 30 cm each are used.
Volume of cube is = side × side × side
Volume of brick = 30 cm × 30 cm × 30 cm
The number of bricks = \frac{\text{Volume of the wall}}{\text{Volume of the brick}}
The number of bricks = \frac{27\times100\times60\times4\times100}{30\times30\times30}
= 6\times4\times100
= 2400
Hence, the number of bricks will be required to be the wall is 2400.
hope it helps.......
