What is the cubic feet calculation for a concrete slab measuring 4 ft x 80 ft and 4 inches thickness?

To find the cubic feet calculation for a concrete slab, you need to use the formula for volume, which is length multiplied by width multiplied by height (or thickness).

First, convert all measurements to the same unit. The thickness of the slab is given in inches, so convert 4 inches to feet:

4 inches = 4/12 feet = 1/3 feet ≈ 0.333 feet.

Now, you can calculate the volume using the dimensions of the slab:

Length = 4 ft

Width = 80 ft

Thickness = 1/3 ft (or approximately 0.333 ft)

Volume = Length x Width x Thickness

Volume = 4 ft x 80 ft x 0.333 ft

Volume = 320 cu. ft. (when you perform the multiplication: 4 * 80 = 320 then multiply by 1/3 to get approximately 106.67 cu. ft.)

The correct answer involves properly calculating the volume using the dimensions provided, leading to approximately 106.67 cubic feet for the slab, which aligns with the answer categorized under option B.

The other options provide either an exaggerated figure based on incorrect assumptions about dimensions or do not accurately reflect the correct calculations of
