To determine how many bags of concrete you need for a 10 x 10 slab, first calculate the volume: a 4-inch thick slab is 10 x 10 x (4/12) = 33.3 cubic feet. A typical 80-pound bag of concrete covers about 0.6 cubic feet. Dividing 33.3 by 0.6 means you would need approximately 56 bags of concrete for that size slab.

To calculate the number of 80-pound bags of concrete needed for a 10 x 10 x 4-foot slab, first determine the volume in cubic feet: 10 x 10 x 4 = 400 cubic feet. Since a standard 80-pound bag of concrete yields about 0.6 cubic feet, divide the total volume by the yield per bag: 400 ÷ 0.6 ≈ 667 bags. Therefore, you would need approximately 667 bags of 80-pound concrete to complete the slab.
To calculate the number of concrete bags needed for a 10x10x2 foot slab, first find the volume in cubic feet: 10 x 10 x 2 = 200 cubic feet. A standard 80-pound bag of concrete typically covers about 0.6 cubic feet. Therefore, you would need approximately 334 bags (200 ÷ 0.6 ≈ 333.33) of concrete to fill that volume.

To calculate the number of 80-pound bags of concrete needed for an 8x10 slab that's 3 inches thick, first determine the volume in cubic feet. The volume is 8 ft × 10 ft × (3/12) ft = 20 cubic feet. Since one 80-pound bag of concrete typically yields about 0.6 cubic feet, you'll need approximately 34 bags (20 cubic feet ÷ 0.6 cubic feet per bag).

To calculate the number of 80-pound bags of concrete needed for an 8x10 slab that's 3 inches thick, first determine the volume in cubic feet. The volume is 8 ft × 10 ft × (3/12) ft = 20 cubic feet. Since one 80-pound bag of concrete typically yields about 0.6 cubic feet, you'll need approximately 34 bags (20 cubic feet ÷ 0.6 cubic feet per bag).
You'll need 1.23 Cubic Yards.

Depends on how thick the slab is, but 4" thick (.33 or 1/3 of a foot thick) would be typical. So multiply 10 x 10 = 100 square feet of area times .33(thickness in feet) equals 33 cubic feet. A 90 lb. bag contains about .66(two thirds) of a cubic foot of concrete, so you would need about 1 1/2 bags per cubic foot or 50 bags for 10'x10'x4"
The number of bags of concrete needed for setting fence posts depends on the size and number of posts. Typically, one 50-pound bag of concrete is enough for one 4x4 fence post. So, if you have 10 fence posts, you would need 10 bags of concrete.

To calculate the volume of a concrete slab, multiply the length, width, and depth. For a 10 x 12 x 4 slab, the volume is 10 feet × 12 feet × 4 feet = 480 cubic feet. Since concrete is typically sold by the cubic yard, convert cubic feet to cubic yards by dividing by 27. Therefore, you will need approximately 17.78 cubic yards of concrete for the slab.
To calculate the volume of a concrete slab, multiply its dimensions: length, width, and depth. For a slab measuring 3 feet by 10 feet by 4 inches, first convert the depth to feet (4 inches = 1/3 feet). The volume is then 3 ft × 10 ft × (1/3 ft) = 10 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 10 by 27, resulting in approximately 0.37 cubic yards of concrete needed for the slab.
