Question

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

Answer 1

Answer:

64 bricks

Step-by-step explanation:

First we calculate volume of wall

16 * 3 * 22.5

1080 m³

Then the volume of bricks

25 * 11.25 * 6

1687.5 cm³

then we will convert 1687.5 cm³ into m³

so,

1678.5÷100 =16.785 m³

for the amount of bricks

1080÷16.785 =

64 bricks
