Where are 12 inch concrete blocks applied?
A concrete block is normally 8 inches high so that an 18 concrete block wall is 12 feet high.

To calculate the number of 6-inch blocks one bag of cement can lay, we first need to determine the volume of one bag of cement. A standard bag of cement typically weighs 94 pounds and has a volume of approximately 1 cubic foot. Assuming the blocks are standard 6-inch concrete blocks (with dimensions of 8 inches by 8 inches by 16 inches), one bag of cement can lay approximately 12 blocks. This calculation is based on the assumption that each block requires about 0.83 cubic feet of concrete, and a bag of cement can yield roughly 1.2 cubic feet of concrete when mixed with water and aggregates.

To determine how many 8-inch concrete blocks fit in a cube, we first need to know the dimensions of the cube. Assuming a cube of 1 cubic foot (12 inches on each side), the volume is 12 x 12 x 12 = 1,728 cubic inches. Each 8-inch concrete block has a volume of 8 x 8 x 16 = 1,024 cubic inches. Dividing the cube's volume by the volume of one block, 1,728 / 1,024, results in approximately 1.6875, meaning only one 8-inch block can fit in a 1 cubic foot cube.

well the density of concrete can vary from 2200kg/m3-2800kg/m3 but 2400kg/m3 is the most common

That depends on how deep (thick) you need it to be. You'll need 1 yard of concrete for every 3/4 inch of thickness of the pad.
usually, it weighs 12 kg.
An 80-pound bag of sacked concrete typically yields about 0.6 cubic feet of concrete. A standard 12-inch concrete block has a volume of approximately 0.5 cubic feet. Therefore, an 80-pound bag can fill about 1 to 1.2 blocks, depending on the specific dimensions and any extra material needed for mortar or adjustments.
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch

The finished block size of a quilt is the size of the block after it is stitched into the quilt. The block size has to include the seam allowances on all four sides. In other words, a 12 1/2 inch block will become a 12 inch finished block.
