To calculate the amount of concrete needed for a 12x30 slab, you first determine the area by multiplying the length (30 feet) by the width (12 feet), which equals 360 square feet. If the slab is to be 4 inches thick, convert the thickness to feet (4 inches = 1/3 feet) and then calculate the volume: 360 square feet x 1/3 feet = 120 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 120 by 27 to find that approximately 4.44 cubic yards of concrete is needed.

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!
3.95 cubic yards of cement are needed for a slab that size.
625 times 0.5 = 312.5 cubic feet will be needed
