It depends on the thickness of slab. A yard of cement contains 9 cubic feet. Thus, it would cover 9 square feet if the slab was 1 foot thick. For a 4 inch thick slab, it would cover 3 times as much area, or 27 square feet.
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
Not counting the space for sand between the blocks, it would take11,520/(area of each block in square inches)blocks.
The answer depends on the size of the cement blocks which are not an international standard.
Because in summers the cement blocks stsrt expanding due t o excessive heat, So to stop it we fill pitch betwwen them which hold the blocks tightly and stop them to contract in winters.if there would be continuous expansion and contraction the cemen blocks would have cracks and they would break down.
A 16 foot by 16 foot block has an area of 256 square feet. It would require 4.836 16 foot by 16 foot blocks to cover an area of 1238 square feet.
Three square feet would cover one square yard or 36 square inches.
That would depend on how thinly you spread it.
Need more info. Would need to know how many square feet one container of cement paint can cover. For example, if one container could paint 100 square feet, you would need 10 containers of paint: 1000/100=10
Spread it evenly, then leave your hands in the cement for 4-6 hours to spread excess cement.
If that is 2' x 4' it would cover 800 square feet. If it is 2" x 4" it would cover about 5.5 square feet.
If the blocks are 12 inches x 12 inches then each block measures 1 square foot. An area of 14 feet x 14 feet has a surface area of 196 square feet, so it would require 196 of the 12" x 12" blocks to cover it.
