The number of concrete blocks that make up a foot depends on the size of the blocks. Standard concrete blocks, often referred to as cinder blocks, typically measure 16 inches long, 8 inches high, and 8 inches deep. To cover a linear foot, you would need about 0.75 of a standard 16-inch block to reach a total of one foot in length.
It is impossible to answer the question as asked because square feet is a measure of area and a "yard of concrete" actually refers to a cubic yard of concrete. However, if we make a couple assumptions we can answer the question I THINK you're asking which is, "How many square feet of concrete does one cubic yard of concrete yield if poured to a typical depth of 4 inches?" The inches of depth can be changed to suit the situation, but in any case giving the poured concrete a depth turns it into a volume which makes it easier to compute the area a cubic yard of concrete will cover. To begin, we need to convertt the square footage of concrete (which is an area) to a volume. Let's use 6 inches for the depth: 12" x 12" x 6" = 864in^3 or 864 cubic inches This is the number of cubic inches of concrete in one square foot of concrete poured to a depth of 6 inches. Now we put a cubic yard into the same terms, cubic inches: 36" x 36" x 36" = 46,656 in^3 or 46,656 cubic inches of concrete. Now we simply divide number of cubic inches of concrete in a yard of concrete by the number of cubic inches in a square foot of concrete poured to a depth of 6 inches: 46656 / 864 = 54 square feet. By the way, there are 27 cubic feet in a cubic yard and you may notice that 27 x 2 = 54. That's a result of the depth I chose for the poured concrete--6 inches. A square foot of concrete poured to a depth of 6 inches is equal to one half cubic foot of concrete. 27 / .5 = 54 If you want to figure square foot yield per yard when you pour the slab at 4 inches instead of 6 inches, then simply substitute 4" in the equations for 6". (36" x 36" x 36") / (12" x 12" x 4") = 81 square feet.
A 16 x 16 is 1.77 sq ft.
An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.
27 cubic yards.will cover 720 square feet @ 1 foot thick
A 16 foot by 16 foot block has an area of 256 square feet. It would require 4.836 16 foot by 16 foot blocks to cover an area of 1238 square feet.
how much does concrete cost per square foot
There are 128 square inches in 8x16 inches. There are 144 square inches in a square foot. So, the side of an 8 x 16 block is a little smaller than a square foot. There are 0.89 square feet in the side of a 8 x 16 block
square foot of what, concrete, wood or paper or what
whats the cost to sandblast concrete persquare foot
8 inch x 16 inch concrete block is actually 2/3 foot x 4/3 foot block Area of one block is 2/3 x 4/3 = 8/9 square feet Number of blocks in 310 square feet = (310)/(8/9) = (310) x (9/8) = 155 x 9/4 which is 1395/4 = 348.75 blocks
Depends on the size of each block.
14 lbs per square foot
Footing for chimneys should usually be double the width of the concrete block. For example, an 8-foot concrete block should have a 16-foot wide footing.
