Question

How many vertices , edges and faces does a octagonal prism have?

Answer 1

$faces = 10 \\ vertices = 16 \\ edges = 24\\ by \: checking \: by \: eulers \: formula \\ f + v = e + 2 \\ 10 + 16 = 24 + 2 \\ 26 = 26 \\ guy \: one \: secret \: for \: finding \: edges \: vertices \: and \: faces \: for \: any \: prism \: there \: is \: one \: formla \\ faces = n + 2 \\ vertices = 2n \\ edges = 3n \\ here \: n \: verifies \: no \: of \: sides$
