Brick wall
A garden 70 m long and 48 m wide should surround by a wall 2.1 meters high and 30 cm thick. The bricklayer will build a wall on the garden ground. How many will we need if 300 bricks are required for approximately one m³?

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
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.
