Question

A pane ,150 m long and 9 m wide , is to be paved with bricks ,each measuring 22.5 cm by 7.5 cm . Find the number of bricks required

Answer 1

☆Hello friend☆

Let's take out atea of pane = 150 m × 9 m
= 1350 m^2

Now, let's take out area of each brick = 22.5 cm × 7.5 cm
= 168.75 cm^2

Number of bricks required = 13500000 cm^2 / 168.75 cm^2
= 80000 bricks
