Two measurements are indication of area. The area would be 144 square inches.
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.
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.
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.
This is a non-trivial question because the curvature of the circle means that in some cases a whole block is required to cover only a tiny part of the circle.Covering a circle with a diameter of 4 feet would require 16 blocks measuring 12 inch * 12 inch. This is despite the fact that the total area of the blocks is more than 27% larger than the area of the circle. This was proved by Maurizio Morandi in May 2009.If the 12 inch blocks are blocks comprising 12 blocks of 1 sq inch each, which can be configured as 2*6 rectangles, or 2+3+3+2+2 shapes, the the problem becomes hugely complex.
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.
The blocks in our grocery are 8 ounce and 12 ounce.

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
