If you mean volume of a trapezoidal prism then it is: 0.5*(sum of parallel sides)*height*length
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.
The volume of a rectangular prism can be found by the formula: volume=length*width*height
Volume = (length) times (width) x (height)
V = l × w × h
area of base x height area of base x height

You must be thinking of a triangular prism. In that case, c is the length of the third side of the triangle at the end of the prism.
Area of trapezoidal cross-section x length.
Volume = (length) times (width) x (height)
Perimeter = area + b1 + b2 + c P = a + b1 + b2 + c
V = l × w × h
To find the volume of a rectangular prism, multiply the base, width, and height. If the prism is irregularly shaped, multiply the base and the height.
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.
