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

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

2.1 * ( 2 * 48 + 2 * 70 ) * 0.3 * 300 = 44604 does the trick

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.
