In a 4-sided pyramid with 4 stacks, the number of balls can be calculated using the formula for the sum of the first n triangular numbers. For 4 stacks, the number of balls is given by the formula: ( \text{Total balls} = \frac{n(n+1)(n+2)}{6} ), where ( n ) is the number of stacks. Plugging in ( n = 4 ), we get ( \frac{4(5)(6)}{6} = 20 ). Therefore, there are 20 balls in the pyramid.

This describes a four-sided pyramid.
if its a four sided pyramid then four. if its a three sided pyramid then four.
A pyramid must have at least four faces (sides) so a three sided pyramid is mathematically impossible.
A pyramid with seven sides has 12 edges. A pyramid based on a seven-sided base has 14 edges.
Eight.

A pyramid with an n-sided base will have n + 1 vertices.
the typical 4 sided pyramid with a square base has 8 edges.
7 faces.
