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.

Trapezoid
Trapezoid. The rectangle, square, and rhombus are all parallelograms. The Trapezoid is a solid: a prism of trapezium cross-section.
With great difficulty because a trapezoid is a 2 dimensional shape which has no volume but it does have a surface area.
The trapezoid is a plane figure which has surface Area, but no volume but if there was a 3d figure your equation would be. The Surface Area of a trapezoid = ½(b1+b2) x h X Height of figure.
Volume = area of pentagon x length of prism.
