"hello students i am data your math leader tutor and the today's question is if a polyhedron has seven faces and ten vertices find the number of edges so we apply in this question we apply the alice formula and according to alice formula we have face plus vertices minus edges is equal to 2 this is the anode's formula now we substitute the values there are seven faces plus 10 vertices minus edges is equal to 2 it means 10 plus 7 17 minus 2 is equal to edges so we got 15 edges so this is our answer i hope you like this video so please subscribe leto for more updates and do comment your questions thank you "
