Jeff started a business to insulate basements and crawl spaces. He uses expanding foam. A litre container will cover 8 m² to a depth of 5 cm. A homeowner has a basement 32' x 42' x 8' in the main section and a cold storage area in the shape of a semi-circle with diameter of 3 m. The walls and ceilings are to be insulated. How large is the surface area to be covered in square footage? Convert the square footage to square meters. How many litres of foam are required?

Notice that the semicircular area will be in square meters. You will have to convert it to square feet.
