A Bezier solid, sliced into pieces. Approximate its volume by a suitable Riemann sum. Each slice has thickness 0.12 cm. The cross-sectional areas (all in square cm) are:[br][br]{2, 1.76, 1.55, 1.35, 1.18, 1.02, 0.89, 0.77, 0.67, 0.59,[br] 0.51, 0.45, 0.4, 0.36, 0.34, 0.32, 0.31, 0.31, 0.33, 0.35, 0.38, 0.43, [br]0.48, 0.55, 0.62, 0.71}[br][br]Find (approximate) the total volume.
