Use euler’s formula to find the number of vertices in a polyhedron with four triangular faces.

Step-by-step explanation:

we know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

Let

V----> the number of vertices

E------> the number of edges

F------> the number of faces

In this problem we have

substitute in the formula and solve for V

see the attached figure to better understand the problem

Lets find how much flour we need for just one serving.

2 2/3 ÷ 6

8/3 ÷ 6

8/3 * 1/6

8/18

4/9 cup of flour per serving

If we triple the recipe (6 * 3 = 18), we will have a total of 18 servings. Multiply the amount of flour we got for one serving to 18 servings.

4/9 * 18/1

72/9

8 cups of flour for 18 servings

Best of Luck!
