The number of bricks of each 15cm x 10cm x 4cm are required to construct a wall of 20m x 10m x 30cm is 10 bricks.
Bricks:
Volume = 15cm x 10cm x 4cm
= 600 cm³
Wall:
Volume = 20m x 10m x 30cm?
= 6,000 cm³
Number of bricks required to construct the wall = Volume of the wall ÷ volume of bricks
= 6,000 cm³ ÷ 600 cm³
= 10 bricks
Therefore, the number of bricks of each 15cm x 10cm x 4cm are required to construct a wall of 20m x 10m x 30cm is 10 bricks
