A 12 inch square block is a sq ft, so 208.
160 sq ft = 160 * 12 *12 = 23,040 sq inches. Each block is 4 * 8 = 32 sq inches so number of blocks needed = 23,040 / 32 = 720.
about 16 cinder blocks
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

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
Where are 12 inch concrete blocks applied?
A 12 inch square block is a sq ft, so 208.

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
1 ft = 12 in → question is how many inch cubes fit in a 12 in by 12 in by 12 in cube. 12 small blocks fit across the front of the box in a row 12 rows of these 12 small blocks fit back from the back in a layer of blocks 12 layers of these blocks fit in the box Thus you will need 12 × 12 × 12 = 1,728 blocks.
Calculate the exterior face area of he wall you want to build and the face area of the side of the cinder block (add about 1/2 inch to length and 12 inch to width for mortar thickness). Divide the wall area by the block area This is the number of blocks you require. This is how I figure out how many blocks you will need: First measure the length of walls for the blocks in feet. Second divide that number by 4 then multiply the total by 3. That will give you total blocks needed for one course of blocks.
To determine how many 12-inch blocks are needed to make a 4-foot circle, we first need to convert all measurements to the same unit. Since there are 12 inches in a foot, a 4-foot circle is equivalent to 48 inches in diameter. The circumference of a circle can be calculated using the formula C = πd, where d is the diameter. For a 48-inch diameter circle, the circumference would be 48π inches. To find out how many 12-inch blocks are needed to approximate this circumference, we would divide 48π by 12 to get the number of blocks required.
