How many cubic feet of soil are in a Triangle with 8 foot sides and 3.5inches deep?

Answer

To find the volume you would first find the area of the triangle (in square feet.) The area of a triangle is 1/2 x base x height. If the triangle is equillateral (all sides the same length) and the sides are eight feet long, then the equation is (1/2) x (8ft) x (8ft) = 32 square feet. Then you take this area and multiply it by the depth. The depth is (3.5/12) because it is in inches rather than feet. So, your answer is 9 1/3 cubic feet.
