A 2ft x 2ft square is 4 square feet and 42 squares will be needed to cover 168 square feet.
2ft by 2 ft = 4 square feet 260 square feet divided by 4 square feet = 65 squares
To do this just multiply together 2ft(*)2ft = 4ft^2 or four feet squared area=lenth times width
30*2 = 60 square feet
Could be a square 2ft x 2ft
In square feet it is 3ft times 2ft = 6 square feet
A = 12.566 square feet.
square feet are converted to square inches by multiplying by 144. IE... 1ft x 1ft = 1sf. 1sf = 144 si. 2ft x 2ft = 4sf = 576si
750, if you need no extra!
