normally, you first need to calculate surface area of the brick which is 12*12=144. then you need to divide total area to bricks surface area which is 48/144.
but probably they gave the units in terms of cm ot metres,then first you need to make them same unit.
To do this you would need to know the area of a brick and the area of the wall. Then you divide the area of the wall by the area of a brick. There are approximately 60 bricks per square metre.
The question, as stated cannot be answered. You need to know two dimensions of the bricks to find the area of each brick, convert that area into square feet (if necessary) and then divide 256 by the area of each brick. Bricks are not usually square so it would not be appropriate for me to assume that the bricks are 16" by 16".
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.
About 14 bricks should do it.
A standard jumbo brick typically measures about 3.5 inches by 7.5 inches. To calculate the number of jumbo bricks in a square foot (12 inches by 12 inches), you can first find the area of one jumbo brick, which is approximately 0.18 square feet. Dividing the area of one square foot by the area of a jumbo brick reveals that there are about 5 to 6 jumbo bricks in a square foot, depending on the exact dimensions of the bricks.

Each brick is 27 square inches. 27*434=11,718 square inches of bricks.

115 should do it!

Gee, a square foot is 12x12, difficult problem.
The area of one 4 inch by 9 inch brick is 36 square inches.The area in square inches of 200 square feet of wall is 28800 square inches (200 x 12 x 12).The number of 36 square inch bricks to cover an area of 28800 square inches is 800 (28800/36).
