boys welcome back this is maths 3000

today we're going to look at working out

the number of vertices on a 3d shape so

the vertices are the same as the cornice

and that is the sharp bits of the 3d

shape so let's start off with our cube

we have one two three four five six

seven eight

so we've got eight vertices for a cube

that's next to our cylinder so honestly

we don't have any sharp corners so we

have zero vertices and finally our

square base pyramid so we have one at

the top and then we've got four around

the bottom there that's a total of five

vertices so thanks for watching guys see

you next time
