The wall is 85 ft x 6 ft = 510 square feet (face area)

One block is 8 inches by 16 inches = 2/3 ft x 4/3 ft = 8/9 square foot.


Divide 510 by (8/9) = 510 x (9/8) = 573.75.


574 blocks. Allow a few extra formistakes!


By the way, check that there will be an even number of rows: 6 ft high = 6x12 = 72 inches. 72/8 = 9. OK, there will be 9 rows of blocks.

How many blocks are in 50 feet?

To determine the number of blocks in 50 feet, we need to know the length of each block. If the blocks are 1 foot long, then there would be 50 blocks in 50 feet. However, if the blocks are, for example, 5 feet long, then there would be 10 blocks in 50 feet. The number of blocks in 50 feet depends on the length of each individual block.


How many blocks equal a mile?

Each city may have a different number of blocks in a mile, as they independently determine the size of their city blocks. There is no universal or standard size for city blocks. To determine how many blocks are equal to one mile, you first need to find the size of the blocks in the city you are asking about, and do the math.5,280 feet equals one mile. To find out how many city blocks would equal a mile, divide 5,280 feet by the number of feet in a block in the city in question.For example, the blocks in Tucson, Arizona are 400 feet long. Diving 5,280 by 400 means that 13.2 blocks would equal 1 mile.Another example, there are long blocks from east to west and short blocks from north to south in Manhattan. There are 20 short blocks in one mile.Depending upon where you are, there are approximately 20 city blocks to one mile.


How many 12 by 12 blocks do you need to make 105 square feet?

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.


How much for block concrete foundation 16 X 60 foot?

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.
