First add the parallel sides: 14 + 8 = 22 Now multiply by the perpendicular height: 22 x 4 = 88 Finally divide your answer by two: 88 ÷ 2 = 44 cm 2. Once we know the area of the cross section we multiply by the length of the prism to find the volume. So 44 x 10 = 440 cm 3. In such case it is called an oblate ellipsoid. If we chop it through the middle to get a circle, then the volume is the area of the circle times 2/3rd of the minor axis.
