Question

How many bricks each of 50 cm x 13.5 cm x 6 cm will be required to build a wall 4 m long, 5.4 m high and 33 cm thick?​

Answer 1

Step-by-step explanation:

We know that volume of cuboid = length × breadth × height

So,

Volume of the brick =25×13.5×6=2025 cm

3

Volume of the wall =800×540×33=14256000 cm

3

Therefore, total number of bricks required =

Volume of each brick

Volume of the wall

=1425000/2025

=7040 bricks

Answer 2

Answer:

we know that volume of cuboid = lengh× breadth× height

so,

volume of the brick= 25×13.5×6=2025cm³

and volume of the wall =800×540×33= 14256000cm³

therefore, total number of bricks required= volume of the wall÷volume of each brick

= 14256000÷2025

=7040 bricks
