So for your 360 sq ft area, this may roughly cost $201. ..., Next, multiply the surface area by the thickness of the slab. Convert the thickness into feet so that you'll get the volume product in cubic feet. This, in turn, makes it simpler to calculate the number of yards you'll need for your concrete order. For example, a 10 x 12-foot slab has an area of 120 square feet., To determine how many bags of concrete you will need, divide the total cubic yards needed by the yields, at 4 inch thick, for a 4×6 slab you will need 0.296 yards of concrete, so number of 80lb bag of concrete = 0.296 ÷ 0.022 = 14 bags, No. of 60lb bag = 0.296 ÷ 0.017 = 18 bags & No. of 40lb bag = 0.296 ÷ 0.011 = 27 bags. ALSO READ :-., We want the wall to be 15 feet high and 30 feet in length. I want to know how many concrete blocks will be required, and an estimate for the cost of the masonry project. Entering these dimensions into the concrete block calculator gives a wall area in square feet of:, With a brief look, a 60x80 area at 6 inches deep, you would need approximately 126.22 tons or 88.89 cubic yards of gravel. Concrete reinforcing is also recommended in high traffic areas and medium to large areas. Wire mesh on average costs $0.56 per sq ft and fiber mesh costs $0.13 per sq ft. So for your 4800 sq ft area, this may roughly cost ..., To determine how many bags of concrete you will need, divide the total cubic yards needed by the yields, at 4 inch thick, for a 8×16 slab you will need 1.56 yards of concrete, so number of 80lb bag of concrete = 1.56 ÷ 0.022 = 71 bags, No. of 60lb bag = 1.56 ÷ 0.017 = 92 bags & No. of 40lb bag = 1.56 ÷ 0.011 = 142 bags., Measure the recommended water amount (each 80-pound bag of concrete mix will require about 3 quarts of water). Step 3. Pour approximately 2/3 of the water into ...
