Question

Find the lateral area of the right prism with height 0.3 dm, if the base of the prism is Isosceles trapezoid with bases of 3 cm and 5 cm, and legs of 4 cm.

1 Answer

  • The lateral area of that prism consists of 4 rectangles.
    h = 0.3 dm = 30 cm.
    The lateral area:
    A = ( a + b + c + c ) · h
    A = (  5 + 3  + 4 + 4 ) · 30
    A = 16 · 30 = 480 cm²
    Answer: The lateral area of the prism is 480 cm².
