how many faces are there in a prism with 24 edges

the number of edges = 3n

the number of vertices = 2n

the number of faces = n+2

where n is equal to the number of sides of polygon bases.

given : 3n = 24 ; i.e. n = 24/3 = 8

thus it is an octagonal prism.

the number of faces = n+2 = 8+2 = 10

hope this helps you
