Baes are isosceles trapeziods with parallel sides that measure 15 cm. and 25 cm. the distance between the parallel sides is 12cm. and the length of each of the equal sides is 13cm. the height of the prism is 20 cm. what is the surface area?

    I can't answer it.

    What are "Baes?"

    Please clarify and repost, using appropriate capitalization and punctuation.

  • geometry - ,

    she probably meant bases

  • geometry - ,

    area of base = (b+B)/2 * h = (15+25)/2 * 12 = 300

    other faces along the length are

    12*20,13*20,25*20

    total surface area is 2*300 + 12*20 + 2*13*20 + 25*20 = 1860
