How many cubic yards of concrete will be needed to pour the slab of the garage?

To determine how many cubic yards of concrete are needed for pouring the slab of a garage, you first need to calculate the volume of the slab in cubic feet and then convert that measurement to cubic yards, as concrete is typically sold in cubic yards.

The volume of a rectangular slab is calculated by multiplying the length, width, and thickness (depth) of the slab. The formula is:

Volume (cubic feet) = Length (feet) x Width (feet) x Thickness (feet)

Once you have the volume in cubic feet, you convert it to cubic yards by dividing the total cubic feet by 27, since there are 27 cubic feet in one cubic yard.

The choice indicating 6.17 cubic yards suggests that after performing these calculations, this volume was obtained, potentially based on realistic dimensions for a garage slab that could range around 20 feet by 12 feet by a thickness of 4 inches.

This choice is a reasonable estimate for a small to medium-sized garage slab, considering that the total volume calculation from the dimensions provided would align with this result after the conversion from cubic feet to cubic yards. This indicates the accuracy of the choice among typical garage dimensions.
