46 bricks; add a few more for waste and cutting
To cover an 81 square foot area, you first need to convert the dimensions of the 12x12 blocks to square feet. Each 12x12 block is 1 square foot (since 12 inches = 1 foot). Therefore, you would need 81 blocks to cover the 81 square foot space.
Well, you've essentially got 27 square feet (9' x 9' x 0.333') which is equal to 1 cubic yard.

There are 2025 rectangles in a 9x9 grid.
That's not possible to tell without more information. Everyone works at different speeds; we have to have at least some information in order to tell.
Assuming 9x9 is also in feet, then answer is 81 square feet.
Well, you've essentially got 27 square feet (9' x 9' x 0.333') which is equal to 1 cubic yard.

Use Pythagoras' theorum a2 = b2 + c2 a2 = (9x9) + (12x12) 225 = 81 + 144 Ö225 = 15cm > 14cm. answer NO.
