30. They would be connected at 12 vertices. Each face (a total of 20 faces) would be a triangle.
If the straw were normal and 8.25 inches then it would take 4.772121212121212... straws.
You would need 12 straws of equal sizes because a cube has 12 equal edges, 8 vertices and 6 faces

According to some definitions an icosahedron is considered a Platonic solid so that each of its faces is an equilateral triangle. You would, therefore need three coplanar isosceles triangles to make each face of the icosahedron. Since there are 20 faces in an icosahedron, you would need 60 such triangles.
