Question

A brick is 25 cm long, 10 cm wide and 5 cm high. How many bricks are required to make a 1 m long wall? (3 Marks)

Answer 1

Length of the wall = 1 m = 100 cm (1 Mark)
Length of the brick = 25 cm (0.5 Marks)
Total number of bricks = $\frac{Lengthofwall}{Lengthofbrick}$
$=\frac{100}{25}=4$ (1 Mark)
4 bricks are required. (0.5 Marks)
