volume of wall = 10 * 10 *12*12 and volume of blocks = 8 * 16

8 x 16 = 128 sq inches there are 12 x 12 = 144 sq inches in one square foot 135 x 144/128 = 152 blocks

A cubic yard is 46,656 cubic inches. Spread to a thicknes of 5 inches, a cubic yard of concrete covers 9332.1 square inches, which is 64.8 square feet.
First you need to tell us what the units of your 8x4 blocks are. For example, feet, or inches.
Assuming each concrete block is 8 inches by 8 inches and the building has walls that are 8 feet high, you would need approximately 1,725 concrete blocks for a 30x50 building. This calculation takes into account the total surface area of the walls that need to be covered by the blocks.
370 8 x 8 concrete blocks equal approximately 164 square feet.
253.125 blocks.
The number of concrete blocks in a cube depends on the size and style of the blocks. For 6-inch by 4-inch by 16-inch blocks, there are generally either 100 or 120 per cube. For blocks that are 8 inches by 8 inches by 16 inches, there are usually either 75 or 90 per cube.

You know the size of a concrete block. They're about $1.50 each at least at my box store. They measure 16" x 8" x 8". Your foundation is 16 feet + 16 feet + 60 feet + 60 feet (assuming it's square since you don't say) = 152 feet linear feet. Thats how far it is to get around your foundation. Next we need to see how many of the blocks we need to get that far. 152 feet x 12 in/foot = 1824 inches divided by 16 inches = 114 blocks for each row you need. You don't say how high the foundation will be. I'm going ot assume 12 feet since you probably have a basement. You can adjust the measurements if you need to. 12 feet x 12 inches per foot = 144 inches divided by 8" (height of the blocks) = 15. So that's 15 rows of 114 blocks each so 15 x 114 = 1710 x $1.50 each = $2565 That's just the cost of the blocks. You need mortar and some skilled labor to set the blocks. You will still need rebar to tie the rows together. Labor to set the blocks. And proper concrete to fill in. And not the kind of concrete you get at the box store.
To determine how many cubic feet of concrete are needed, you first need to know the depth of the concrete slab. For example, if the slab is 6 inches thick, you would multiply 360 square feet by the thickness in feet (6 inches = 0.5 feet) to get 180 cubic feet of concrete required.
