Estimate the volume of concrete (in cubic yards) needed to place the continuous footings shown in the figures below. Assume a waste factor of 7%.
The area has six sides and the angle between each set of adjacent sides is 90 degree. The length of the sides in feet are as follows: 22, 20, 8, 25, 30, and 45.
The size of the footing is 2 feet and 6 inches wide by 1 foot thick. The footing has four continuous number 4 rebar and one number 5 dowel spaced at 12 inch apart.
