The perimeter of a square is calculated by the formula ( P = 4s ), where ( s ) is the length of one side. If the perimeter is 3 feet, then each side is ( s = \frac{3 \text{ feet}}{4} = 0.75 \text{ feet} ). Since there are 12 inches in a foot, ( 0.75 \text{ feet} \times 12 \text{ inches/foot} = 9 \text{ inches} ). Therefore, each side of the square is 9 inches long.
1 foot = 0.3048 metres.
Multiply 4 time 8 to get 32 square inches for each brick, then divide 32 by 144, the area of a square foot, to get 0.22222etc, then divide 175 by the 0.22222 to get 787.5 or 788 bricks if you can only have whole bricks.
