81.
12 feet = 144 in, which is exactly 9 x 16. 9 - 16" bricks on a side, 9 x 9 = 81 bricks.
The answer will depend on the size of the bricks!
If the bricks are in feet then 51/2 bricks would be needed.
That depends - whether your 4x8 bricks are in centimetres, metres, inches or feet.
450 bricks
About 14 bricks should do it.
115 should do it!
1,350 of them.
Is that 144 square feet, as in 12' x 12'?If that is the case, you would need a minimum of 81 bricks. If the patio is indeed square, or 12' by 12', each side is 144", or 9 16" bricks. 9 x 9 = 81 bricks.If the patio is not square, you may need extra bricks on one or both sides if the width is not evenly divisible by 16 inches.
The answer will depend on the shape of the patio. If it curved then some bricks will need trimming and that will result in wastage and so a larger number of bricks will be required. Also, if the patio leaves a small fractional amount after a whole number of bricks, you will need a lot more bricks. As an extreme example, if the patio is 8 cm*625 metres then you will need 3125 bricks. However, if the shape is convenient, you will require 2500 bricks.
