How many bricks will be required for constructing a wall which is 16 m long, 3 m high, and 22.5 cm thick, if each brick measures 25 cm x 11.25 cm x 6 cm?

उत्तर
Length of the wall = 16 m = 16 x 100 cm = 1600 cm
Height of the wall = 3 m = 3 x 100 cm = 300 cm
Breadth of the wall = 22.5 cm
Volume of the wall = 1600 x 300 x 22.5 cm3 = 1,08,00,000 cm3
Volume of one brick = 25 x 11.25 x 6 cm3 = 1687.5 cm3
Number of bricks required to construct the wall = `"Volume of wall"/"Volume of one brick"`
= `(1,08,00,000)/1687.5 = 6400`
