Answer:
The answer is A. The volumes are the same
Explanation:
First you have to determine the area of the cross sections for each of them.
The area of the rectangular cross section will be:
A= 7(6)
A= 21 cm²
The area of the triangular cross section will be:
A=
(7)(6)
A= 21 cm²
So, they both share the same area which Cavalieri's Principle said that if two solids of equal height have equal cross-sectional area at every level, then the volume are the same.
