How Many Courses?
Using the brickwork dimension
table provided by your course
tutor, you can identify how
many courses of brick
are required to build a
brick wall of a
specific height.

A Square Metre of Brickwork
In every square metre of half brick walling there are 60 bricks. We
can calculate this by working out the surface area of one brick
(including mortar) and seeing how many times it fits into an area 1m
long and 1m high.

How Many Bricks?
Before a bricklayer starts a project they will calculate the number of
bricks required to complete the project. They can then order the bricks
knowing they will have enough materials (but not too much).
To calculate the number of bricks required for a half brick wall you
multiply the surface area by 60 as there are 60 bricks per square metre.
Activity 3
Number of Bricks = Surface Area x 60
Number of Bricks = (10 x 3) x 60
Number of Bricks = 1800
The wall shown is 10m long and 3m high. How many bricks are required
to build the wall?
3m
10m
Activity 4
Number of Bricks = Surface Area x 60
Number of Bricks = (8 x 2.6) x 60
Number of Bricks = 1248
The wall shown is 8m long and 2.6m high. How many bricks are required
to build the wall?
2.6m
8m
Activity 5
Number of Bricks = Surface Area x 60
Number of Bricks = (6 x 1.5) x 60
Number of Bricks = 540
The wall shown is 6m long and 1.5m high. How many bricks are required
to build the wall?
1.5m
6m
