There are two rectangular prisms. The base of the first prism is a 3-in-by-3-in square. The base of the second prism is also a square
whose side is 1 inch shorter. One prism is 10 inches taller than the
other prism. If both prisms have the same volume, what is the
volume of each prism in cubic inches?

3 cubic inches

Step-by-step explanation:

v= 1/2 * b*h

v = 1/2 * 3*3

v =3 cubic meters

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
