To calculate the volume of concrete in a pad measuring 3 feet by 8 feet by 4 inches, first convert the thickness from inches to feet: 4 inches is 1/3 of a foot. Then, calculate the volume by multiplying the length, width, and thickness: 3 ft × 8 ft × (1/3 ft) = 8 cubic feet. Therefore, the pad contains 8 cubic feet of concrete.
To calculate the amount of concrete needed for a 14x12 foot pad that is 4 inches deep, first convert the depth to feet: 4 inches is 1/3 of a foot. Then, calculate the volume: 14 ft x 12 ft x (1/3 ft) = 56 cubic feet. Since concrete is often sold by the cubic yard, convert cubic feet to cubic yards by dividing by 27: 56 cubic feet ÷ 27 = approximately 2.07 cubic yards. Therefore, you should buy about 2.1 cubic yards of concrete, accounting for some extra for spillage or over-excavation.
Oops . . . please repost your question and include the depth of the concrete. You have to have all 3 dimensions in order to calculate volume (Cubic Yards of concrete).
Use the metric system, it's more practical. Just do width * height * lenght of the area. This will get you something in CM^3. Then just do / 100^3 and you have M^3, the bags of concrete you buy will say how much M^3 you can pour with it.
One yard of concrete will cover approximately 90 square feet at a depth of 3-1/2". At an even 3-1/2", you will need just over 3 yards. This does not allow for any footings, turndowns, or a thicker slab.
15X15X.33(4/12 there is 4 inches in a foot therefor 4" is .33 of a foot) equals 74.25 cf of concrete divide by 27 (three demensional object for yards) 2.75 Cubic Yards. if you try to order .75 cubic yards of concrete you will be laughed at, just order 3 cubic yards and make a entrance path. good luck.
2000 pounds
That depends on how deep (thick) you need it to be. You'll need 1 yard of concrete for every 3/4 inch of thickness of the pad.

To calculate the number of 80 lb bags needed for a 3x4x3 pad, first determine the volume of the pad in cubic feet: 3 ft x 4 ft x 3 ft = 36 cubic feet. An 80 lb bag of concrete typically covers about 0.6 cubic feet. Therefore, you would need approximately 36 / 0.6 = 60 bags of 80 lb concrete to fill the pad.
Most bags will make a 1/3 of a cubic foot of concrete.
(x2 - 3)(x2 + 3)(x4 + 9)
3 cubic feet of it.
How mush is a price of 5 yards of concrete delievered
1 60lbs bag makes around a 1' by 1' by 3" thick pad..
To calculate the amount of concrete needed for a 14x12 foot pad that is 4 inches deep, first convert the depth to feet: 4 inches is 1/3 of a foot. Then, calculate the volume: 14 ft x 12 ft x (1/3 ft) = 56 cubic feet. Since concrete is often sold by the cubic yard, convert cubic feet to cubic yards by dividing by 27: 56 cubic feet ÷ 27 = approximately 2.07 cubic yards. Therefore, you should buy about 2.1 cubic yards of concrete, accounting for some extra for spillage or over-excavation.
96 cubic feet of concrete
