If two distinct prisms have bases of equal area and altitudes of equal length, then
a. their volumes are equal
b. their lateral areas are equal
c. their total areas are equal
d. they have the same number of faces

A. their volumes are equal

Step-by-step explanation:

we know that

The volume of a prism is equal to

where

B is the area of the base and H is the height of the prism

therefore

If two distinct prisms have bases of equal area and altitudes of equal length, then

Their volumes are equal

The other options not necessarily must be true

you answer is a

step-by-step explanation:

only 10/60 isn't equivalent

hope this : )
