# Brick wall

Garden 70 m long and 48 m wide should surround with wall 2.1 meters high and 30 cm thick. Wall will be built on the garden ground. How many will we need bricks if to 1 m³ is required approximately 300 bricks?

Result

n =  44378

#### Solution:

Leave us a comment of example and its solution (i.e. if it is still somewhat unclear...):

Math student
unprecise - need to know if wall needs to be build ON garden-ground (like in the solution) or if wall should enclose whole garden - in that case:
2.1 * ( 2 * 48 + 2 * 70 ) * 0.3 * 300 = 44604 does the trick

Dr Math
thank you, we corrected the wording of the problem. But your solutions 44604  tricks is also wrong because in the corners some bricks are not counted.

#### To solve this example are needed these knowledge from mathematics:

Do you want to convert area units? Do you know the volume and unit volume, and want to convert volume units?
