Question

How do you find the volume of a 3D trapezoid?

Answer 1

Find the area of just the trapezoidal face `A=1/2h(b_1+b_2)`, then multiply it by the length of the entire prism.

Answer 2

As below.

Explanation:

Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2.

In other words, multiply together the length, height, and average of A and B.
