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
Turn the feet into inches then divide by 8 for the height and 16 for the lenth. EXAMPLE - 24ft long times 12 inches = 288 in. divided by 16 = 18 block long. 8ft high times 12 inches = 96 in. divided by 8 = 12 block high. The typical cinder or concrete block in the US is 15-5/8 long x 7-5/8 tall, with a mortor joint of 3/8 in. its measures 16 in. x 8 in. Dont forget your interior walls where bearing is needed. With wood beams these are needed every 16ft. With metal, the sky is the limit, although the steel beams must be built per size. Also there are many different size thicknees, the typical is 8 in. so the block will be a 8x8x16 in block. They also comes in 4 in. in this case the block is a 4x8x16. 12 inches is a foot but keep in mind that 16 inches is a linear foot.
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.
The average installation price of a concrete patio per square foot in OK is close to $4. This amount would include everything.
== == A square foot is a (two dimensional) measure of area, while a ton is a measure of weight. The two do not equate. On the other hand, a ton of a specific substance could have a specific (three dimensional) volume. For instance, if a one cubic foot concrete block weighed 100 pounds, 20 concrete blocks would equal a (US) ton.
It costs an average of $3.10 a square foot for asphalt. It costs on average $4.85 a square foot for concrete.
