Well, isn't that a lovely question! To calculate the amount of concrete needed for a slab, you'll need to consider the thickness of the slab. On average, for a 10cm thick slab, you would need about 0.8 cubic meters of concrete for 8 square meters. Just remember to always double-check your calculations and enjoy the process of creating something beautiful!

A 22x22 foot slab at a 4-inch thickness/depth requires a minimum of 6 cubic yards.
1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.
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.
