25*18*x = 225
x = 225/(25*18) = 225/450 = 1/2 ft

To find the thickness of the concrete slab, we'll use the formula:
Volume = Length x Width x Height
In this case, we know the volume (225 cubic feet) and the length (25 feet) and width (18 feet) of the slab. We need to solve for the height (thickness) of the slab.
Plugging in the known values:
225 cubic feet = 25 feet x 18 feet x Height
To find the height, we can rearrange the equation:
Height = Volume / (Length x Width)
Height = 225 cubic feet / (25 feet x 18 feet)
Height = 225 cubic feet / 450 square feet
Height = 0.5 feet (or 6 inches)
Therefore, the thickness of the concrete slab is 0.5 feet (or 6 inches).
