If it is a rectangular trapezoidal pedestal: Calculate the area of the base of the pedestal, multiply by the height of the pedestal.
If the angles of the pedestal are not 90deg.. i.e. if it is a pyramidal trapezoidal pedestal.
Then calculate the volume as you normally would a rectangular trapezoidal pedestal, and subtract the volume of the missing triangular pieces with the formula 1/3 area of base X height.

What is the formula for volume of concrete footing in trapezoidal?
volume=h/3(A1+A2*Under root A1*A2)
Is there a 3-d shape for a trapezoid?
Yes, it is called a Trapezoidal or a Trapezoidal Prism.
How many vertices does a trapezoidal prism have?
A trapezoidal prism has 8 vertices:A trapezoid has 4 vertices.A trapezoidal prism is composed of 2 trapezoids. 2 X 4 = 8.
What is the volume of a trapezoid prism?
The volume of any right prism is the area of the base, in this case a trapezoid, multiplied by the height of the prism. The formula for the area of a trapezoid is A = 1/2h(a + b) where a and b are the bases of the trapezoid (the parallel sides). Once you calculate the area of the trapezoidal base of the prism, multiply that number by its height to get its volume.
Is a trapezoidal prism a polyhedron?
Yes, a trapezoidal prism is a polyhedron. A polyhedron is a solid three dimensional object with flat face, straight edges and sharp corners.
