Best Answer

the volume of a trapezoidal prism is equal to the height times the base area of the trapezoid.

First you find the area of trapezoid h(a+b)/2

h is the height of the trapezoid, not the height of the prism

a is the length of the top

b is the length of the bottom

Then you find the volume of the trapezoidal prism with this formula H*h(a+b)/2

H is the height of the prism.

Multiply H by the area of the trapezoid that you found in step one.

If you mean volume of a trapezoidal prism then it is: 0.5*(sum of parallel sides)*height*length

Volume = 1/2*(a+b)*h*l where a and b are the lengths of the parallel sides of the trapezium, h is the height of the trapezium, and l is the length of the prism.

It is the area of the trapezoidal face multiplied by the length of the 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.
