You literally just plug in your given values into Euler's characteristic and solve.

   V - E + F = 2
11 - E + 10 = 2
     - E + 21 = 2
              21 = 2 + E
              19 + E

Therefore it has 19 edges.

Joe used 16 ounces of dark chocolate while baking. He used to fifths of the chocolate to make some frosting and use the rest to
Oduvanchick [21]
He used 16 oz of dark chocolate........he used 2/5 to make frosting....meaning he used 3/5 for the brownies.

2/5(16) = 32/5 = 6.4 oz for frosting
3/5(16) = 48/5 = 9.6 oz for the brownies

Therefore, he used (9.6 - 6.4) = 3.2 more oz in the brownies then in the frosting
