The width of a wall is 22m and its height is 3.5m How many bricks of length 22cm and width is 7 cm can make a single wall?

Width = 22m

Height = 3.5m

--- Convert both of these into cm to convert into same units

Width = 22 x 100

= 2200cm

Height = 3.5 x 100

= 350cm

Next find the area of the wall

---Area of rectangle = height x width

Area of the wall = 2200 x 350

= 770,000 sq. cm

Now for the bricks

Length = 22cm

Width = 7cm

Area = 22 x 7

= 154 sq.cm

To find the number of bricks needed we have to divide the area of the wall with the area of one brick

770,000 / 154

=5000

Therefore 5000 bricks are needed to make a single wall
