A new two-story house has basement dimensions of 52 feet by 28 feet, with a 20 foot by 22 foot attached garage. How much concrete will be required to pour the basement walls?

To determine the amount of concrete required to pour the basement walls, you need to calculate the surface area of the walls and then convert that into volume using the thickness of the walls.

First, calculate the perimeter of the basement, which is essential to find the total wall area. The basement dimensions are 52 feet by 28 feet. The perimeter can be calculated using the formula for the perimeter of a rectangle:

Perimeter = 2 × (Length + Width) = 2 × (52 + 28) = 2 × 80 = 160 feet.

Next, you'll need to determine the height of the walls. In residential construction, basement walls are often around 8 feet high, although this can vary.

Now, calculate the total surface area of the walls:

Area of walls = Perimeter × Height = 160 × 8 = 1280 square feet.

To convert the surface area into volume, you also need to consider the thickness of the walls. Assuming an average wall thickness of about 1 foot (this can vary, so refer to local building codes for specifics), the volume of concrete required can be calculated by multiplying the total wall area by the thickness:

Volume = Surface Area × Thickness = 128
