Volume of right prism:
What information do we have?
Height of base = 5 ft
Length of first parallel line = 5 ft
Length of Second parallel line = 8 ft
Volume of prism = 240.5 ft³
Volume of prism = Area of base × height
Volume of prism = (1/2)(sum of parallel line)(Height) × height
240.5 = (1/2)(5+8)(5) × height
240.5 = (1/2)(13)(5) × height
240.5 = 32.5 × height
Height of prism = 7.4 feet
