Change all the units to the same unit, feet or inches.
3 inches is 1/4 of a foot, 0.25.
Multiply 10x22x0.25=55 cubic feet.
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.
It is the area of the trapezoidal face multiplied by the length of the prism.

A trapezoidal prism
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.

A trapezoidal prism has 8 vertices:A trapezoid has 4 vertices.A trapezoidal prism is composed of 2 trapezoids. 2 X 4 = 8.
It is: 0.5*(sum of parallel sides)*height*length measured in cubic units
If the VOLUME is 999 SQUARE inches then you have gone wrong. SQUARE inches are a measure of AREA VOLUME is measured in CUBIC units. Assuming you meant The volume of a prism is 999 CUBIC inches, then the volume of a pyramid with the same height is indeterminate (cannot be given), as there is NO INDICATION of how the height of the pyramid relates to the height of the prism. So, ASSUMING you mean the volume of a prism is 999 CUBIC inches AND the HEIGHT of the pyramid is the same as the height of the prism, then the volume of the pyramid is one third that of the prism, ie 999 cu in ÷ 3 = 333 CUBIC inches.
