How many cubic feet of concrete are in a slab that is 5 feet wide, 6 feet long, and 6 inches deep?

To calculate the volume of a concrete slab, you can use the formula for volume, which is length × width × height (or depth). In this case, the slab dimensions are given in feet for width and length, but the depth is provided in inches. First, it is important to convert the depth from inches to feet. Since there are 12 inches in a foot, a depth of 6 inches is equivalent to 0.5 feet.

Now substituting the values into the formula, we have:

• Length = 6 feet

• Width = 5 feet

• Depth = 0.5 feet

Calculating the volume involves multiplying:

Volume = Length × Width × Depth

= 6 feet × 5 feet × 0.5 feet

= 30 cubic feet × 0.5

= 15 cubic feet

Thus, the volume of the concrete slab is 15 cubic feet. This is why the correct answer is accurate and reflects the necessary calculations for determining the volume of the slab.
