On average, 8 cubic feet of concrete can weigh around 4,000-4,500 pounds, depending on the density of the concrete mix.
For a 1000 sqft slab with a thickness of 4 inches, you would need approximately 33 cubic meters of concrete. This calculation is based on the assumption that 1 cubic yard of concrete covers 81 square feet at 4 inches thick.
Lightweight concrete typically weighs between 90-115 pounds per cubic foot, which is significantly less than standard concrete that weighs around 140-150 pounds per cubic foot. The lower weight of lightweight concrete is achieved by incorporating lightweight aggregate materials, such as expanded clay, shale, or slate.
To figure out consider this: a dumpster that can enclose 30 cubic yards would have the dimensions approximately of :6feet tall, 22 feet by length and 8 feet wide
The weight of one cubic meter can vary depending on the substance being measured. For water, one cubic meter weighs approximately 1000 kilograms (or one metric ton). However, for other materials like concrete or steel, the weight of one cubic meter will be different.
I don't think you can convert a cubic dimension into a squared dimension as a cubic dimension applies to volume and a squared dimension applies to area. Length X Width = Area (squared dimension); Length X Width X Depth = Volume (cubic dimension). One square yard = nine square feet; One cubic yard = 27 cubic feet.
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.

Concrete weighs about 150#'s per cubic foot. Given that your measurements are 2'x2'x4', the block contains about 16 cubic feet. 16 cubic feet of concrete at 150#'s is about 2400#'s per block.
2.5 cubic feet of water weighs about: 156 pounds.
An 80 pound bag of premix concrete will make .6 cubic feet of cured concrete. There are 27 cubic feet in a cubic meter, so it would take 45 80 pound bags to make one cubic meter.

An 80-pound bag of premixed cement = .667 cubic feet, or 2/3 of a cubic foot, of concrete. A 60-pound bag of premixed cement = .5 cubic feet, or 1/2 of a cubic foot, of concrete.
(3.5/12) x 120 = (.2917) x 120 = 35.004 Cubic Feet Concrete is sold by the cubic yard. 35.004 cubic feet = 1.3 cubic yards
Roughly 10 cubic yards (or 270 cubic feet).
To calculate the amount of concrete needed for a 12x12x4 slab, first convert the dimensions to feet: 12 feet by 12 feet by 4 inches (which is 1/3 foot). The volume in cubic feet is 12 x 12 x (1/3) = 48 cubic feet. Since concrete is typically sold by the cubic yard, divide the volume by 27 (since there are 27 cubic feet in a cubic yard): 48 ÷ 27 ≈ 1.78 cubic yards of concrete is required.
