Question

a wall was to be bulit across an open ground to cover a width of 10 cm the hight of the wall is 4nm and the thickness of the wall is 24cm if the wall is to be built up with bricks whose dimensions are 24 12 8 how many bricks would be required​

Answer 1

Answer:

length of the wall, l = 10 m = 100 cm

Breadth of the wall, b = 42 m = 4200 cm

Height of the wall, h = 5 m = 500 cm

Volume of the wall = l × b × h = 100 cm × 4200 cm × 500 cm = 21000000 cm3

Dimension of the brick = 42 cm × 12 cm × 10cm

∴ Volume of each brick = 42 cm × 12cm × 10 cm = 5040 cm3

Let the number of bricks required be n.

n × Volume of each brick = Volume of the wall

therefore, n= vol of the wall/ vol of each brick

n= 21000000cm³/5040cm³

n= 4166.67

Thus, the number of brick required is 4166.67
