Question

A solid faces that consist of 1 pentagon 5 congruent equilateral triangles and 5 congruent squares. The solid has 11 vertices. How many edges does this solid have?

Answer 1

hmm

Answer 2

are u given a formula linking face edges and vertices

Answer 3

for 11 vertices
there a total of 11 Choose 2 ways of possible orientations of lines

Answer 4

a pentagon has 5 sides
triangle has 3, u have5 of those 5*3
and 5*4
a total of
20+15+5 = 40sides

Answer 5

not these sides are shared between each other and all together have only 11 vertices

Answer 6

lets see
okay lets tart with the pentagon
5 edges there
now lets add 5triangles to to 5 of those edges are all used for the 5 triangles
and the upper lines for the triangles are shares between each triangle too so
6 unique extra lines
a total of 5 + 5 verticles so far..
