Assuming 2 dice, 6 ways:
1+6, 2+5, 3+4, 4+3, 5+2, 6+1
how many ways can you get a sum of 1?
There are infinitely many ways to get this sum.
1
An infinite number.
There are infinitely many ways.
one base nine faces
10 ways.
An infinite number of ways.
6 faces 12 edges 8 corners The sum equals 26 of all three parts combined.
A rectangular-based pyramid has 5 faces, 8 edges, and 5 vertices. To check if the numbers are right, the Euler's rule can be used. The formula is Faces + Vertices = Edges + 2. Clearly, the sum of the faces and vertices, which is 10, is equal to the sum of the edges plus 2, which is also 10.
A shape does not have a sum. You can sum its angles, the lengths of its sides, the areas of its faces and so on. But the shape does not have a sum, in itself.
There are an infinite number of ways to do that.
