given:
the Length, breadth and height of a wall is 5m,30cm and 3 m
find:
how many bricks of dimensions 20cm ×10 cm× 7.5 cm are required to build the wall
solution:
vol of the wall = 5 x 3 x 0.30= 4.5 m³
vol per brick = 0.20 x 0.10 x 0.075 = 0.0015 m³
number of bricks = <u> wall volume </u>
vol. per brick
= 4.5 / 0.0015
= 3000 pcs of bricks required
