Assuming they are 8 inch*16 inch blocks, 144 square feet = 144*12*12 square inches. So number of blocks required = 144*12*12/(8*16) = 162
720 4"x 8" tiles are needed.
2.78 square feet.
8 inch x 16 inch concrete block is actually 2/3 foot x 4/3 foot block Area of one block is 2/3 x 4/3 = 8/9 square feet Number of blocks in 310 square feet = (310)/(8/9) = (310) x (9/8) = 155 x 9/4 which is 1395/4 = 348.75 blocks
It depends on whether the blocks are laid with a 8x8 face up or 8x16.

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
2.78 square feet.
2.77 square feet.
More information is needed EG what type of 12 inch blocks there are many(see link below). Also what way up are you using these blocks. http://www.boralbestblock.com/product-lines/masonry/standard-block/12-inch-block
