Be more specific with your question. Are the blocks measured in inches, feet, millimeters, centimeters etc. Same applies to the area.

Multiply width by length to get the area. The answer would be 256 square feet or 28.45 square yards.

The answer depends on the measurement units used for 16x16. The answer also depends on the shape of the 390 sq ft area to be covered because the more irregular the shape, the greater the number of pavers you will need to cut. That is likely to result in some breakage. Furthermore, you may not want to use all the offcuts since that will make part of the area into a mosaic.
144/2.25=64. 18x18 tile cover 2.25 sq ft area.
If you have an eight square foot area, and the tiles are 112x12-inches, you will need eight. If what you meant to say was an eight foot square area, that would be 64 square feet, and you would need 64 tile. Sorry! In the first line above should read, "...and the tiles are 12x12-inches..."
12 x 12 blocks (assumed as 12 inch x 12 inch) That means the blocks are 1 square foot each Hence to cover 240 square feet area, you would need 240 blocks
Assuming you mean 16x16 inches tiles... 441 tiles would cover the area exactly
12X12 12X12
49 plus ten percent for breakage. Get 54.
Gee, a square foot is 12x12, difficult problem.
144
78.47 Pavers
The tile is bigger than the area that you want to cover (12x12 > 10x11) so one tile will do. <><><><><> However, if you meant 12x12 INCH tiles, and a 10x11 FOOT room, you would need 110 tiles.
Multiply width by length to get the area. The answer would be 144 square feet.
