Aright rectangular prism has a height of 15 in, and the area of the cross section taken parallel to the base at a level of 5 in above the base is 25 in2. a right triangular prism has a height of 15 in, and the area of the cross section taken parallel to the base at a level of 5 in above the base is 25 in2. do the solids have the same volume?
a.
yes, because they have the same height and the same cross-sectional area at every level parallel to the bases.
b.
yes, because the solids are congruent.
c.
no, because the heights are not equal.
d.
no, because the cross-sectional area at every level must be the same, not just at one level.
