Answer 1

Answer:

$Leonhard \: Euler \: was \: a \: Swiss \\ mathematician \: who \: was \: one \: of \\ the \: greatest \: and \: most \: productive \\ mathematicians \: of \: all \: time. \\ He \: spent \: much \: of \: his \: career \: blind, \\ but \: still, \: he \: was \: writing \: one \: paper \\ per \: week, \: with \: the \: help \: of \: scribes. \\ Euler \: gave \: one \: very \: popular \\ formula \: called Euler’s \\ Polyhedral formula. \\this \: formula \: is \: not \: for \: only \\ \: polyhedron \: shape \: but \: for \: all \: \\ shapes \: with \: different \: formula \\ for \: this \: question \: we \: hve \: to \: only \\ read \: polyhedron \: formula \\ \\ \\ given \: = 6 \: faces \: and \: 5 \: vertices \\ formula \: = F+V = E+2 \\ 6 + 5 = E + 2 \\ 11 = E + 2 \\ 11 - 2 = E \\ 9 = E \\ edge \: = 9$
