Answer 2

Answer: B) Elena incorrectly used slant height instead of the height

--------

When finding the volume of a rectangular pyramid using the equation
`V = (1)/(3) Bh`, B = area of base of the pyramid and h = height of pyramid.

Elena correctly put in the area for the base of the pyramid (8*10 = 80), but she put in the slant height (15) instead of the the height (12).
