Answer:1920 cm^3Step-by-step explanation:Divide into the rectangular prism on top, and the one on the bottom. Whole = sum of parts, so you find the volumes of those two separately and add them together to get the total.V of rectangular prism = l x w x h (length x width x height)Top:l = 10w = 8 h = 14 - 10 = 410 x 8 x 4 = 320Bottom:l = 10 + 10 = 20w = 8h = 1020 x 8 x 10 = 16001600 + 320 = 1920
