Volume of a triangular prism:1000 cu ft

Length of base: ??

Height of base: 2ft

Height of prism:40ft

  • Algebra -

    Volume = (1/2) b h L = L*(base area)

    If 40 ft is the LENGTH L of the prism, the base area is 1000/40 = 25 ft^2.
    Then, since (1/2) b*h = 25
    base length b = 25*2/h = 25 ft
    (if h = 2 is the base height)
