Kendra used 225 cubic feet of concrete to make her new patio. The patio is a rectangular concrete slab and measures 25 feet by 18 feet. How thick is the concrete slab?
This problem clearly states how to solve it. Use the information you already know to solve.
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).
