Answer 2

There are 9 edges in a triangular prism. An edge in a solid is defined as the line joining two surfaces in the solid.

There are 9 edges in a triangular prism. In a triangular prism, there are 5 faces, two triangular faces, and three rectangular faces joining consecutive sides of the two triangles.

Answer 3

Thank you both :)

Answer 4

btw you need to use `Euler formula` for this

Answer 6

\(V-E+F = 2\)

Answer 7

\[\huge a = \frac{ A_l }{ h }.c.b\]

Answer 8

What ganeshie gave is also correct it is the Euler formula

Answer 9

Thanks again @ganeshie8 :)
Thank you Michio...

Answer 10

b -Base side
A(l) - Lateral surface area
c-Base side
h- height

Answer 11

interesting, what that formula does @Michio_kaku ? is that from topology ?

Answer 12

oh not this again. lmfao

Answer 13

lol ive never seen that formula before

Answer 14

It is from euclidean geometry.

Answer 15

Well , you may say its from topology

Answer 16

I'm not sure I understand what it does :
lets take a triangular prism,
b = 1
h=1
c=1
A(l) = 3

pluggin them in ur formula gives :
a = 3

Answer 17

whats the interpretation for the value of "a" ?

Answer 18

a is the Base side

Answer 19

Which can also be termed as a edge

Answer 20

I'm bit lost on this >.<

Answer 21

Never mind.

Answer 22

care to elaborate a bit more, or got any links explaining the formula ? :)

Answer 23

I read this formula in a book , I don't have any website links
