Multiply the square footage by the depth in feet to find the volume of the space in cubic feet. Volume is found by measuring length × width × depth. Finally, divide the cubic footage by 27 to find the volume in cubic yards. This is the amount of concrete needed.

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.

Multiply the square footage by the depth, such as 60 times 0.167 for about 10 cubic feet. When you divide the cubic feet by 27, you get the number in cubic yards. If you had 120 cubic feet, for example, divide 120 by 27 to get about 4 1/2 cubic yards. If you need the amount in tons, multiply the cubic yards by 1.35.

The mix: 1:3:6 for cement: fine aggregate (sand): coarse aggregate (granite) by mass (kg). Therefore, The mass of cement required= 0.0228 * 1440 = 32.832 kg. The number of bags of cement required= 32.832/50 = 0.66 bag (ie 1 bag of cement is required to cover a 1m * 1m * 0.15m floor in a concrete mix 1:3:6).

Measure the length and height of the block in inches and then substitute the values in the equation square feet of block = (length of block x height of block) / 144. For example, a standard cement block measures 16 x 8 inches, so it covers 0.89 square feet — (16 x 8) / 144 = 0.89.

Overall, concrete is an affordable material, particularly when you compare it to stone or other construction materials. In general, you should expect to pay around $6 per square foot for a concrete slab to be installed. For a typical 30-by-30-foot slab, it should cost between $3,600 and $7,200.

Measure the recommended water amount (each 80-pound bag of concrete mix will require about 3 quarts of water). Pour approximately 2/3 of the water into the depression.

One 50-pound bag of Quikrete Fast Setting Concrete Mix yields about . 375 cubic feet. For example, if you need to cover 33.333 cubic feet, using 60-pound bags of concrete, divide 33.333 cubic feet by .

To calculate the occupant load, the first step is to calculate the area of the space in question by multiplying the length times the width – typically measured within the interior faces of the walls. For example, if a classroom measures 30 feet by 40 feet, the nominal area is 1,200 square feet (30' x 40' = 1200 SF).

Concrete costs from $113 to $126 per cubic yard or between $2.83 to $3.57 per square foot depending on the thickness of the slab poured. It will cost an additional $2.52 to $2.60 per square foot for the labor.

Measuring the Driveway To measure the driveway in cubic feet, multiply the length by width by depth. For cubic yards, divide the total cubic feet by 27. Because one cubic yard of gravel is equal to 1.13 tons, you can multiply your total cubic yards by 1.13 to convert this measurement to tons.

Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 21.6 (the amount of cubic feet in a ton). The final figure will be the estimated amount of tons required.

Calculate Concrete Volume With the volume of the submerged post and the volume of the hole figured out, subtract the post volume from the hole volume and you will have the volume of concrete needed for each hole. Simply multiply that amount times the number of posts to get a total quantity.
