Work out shape sides and corners instantly with clear inputs, formula shown and shareable results.
Every polygon has as many corners as sides, so the totals are simply sides-per-shape multiplied by the number of shapes; a circle contributes none of either. Counting sides and corners across a group of shapes is early multiplication in disguise, and the circle case teaches that not every shape has vertices.
Totals
total sides = sides per shape x number of shapes; corners = sides for any polygon
total sides = sides per shape x number of shapes; corners = sides for any polygon. Every polygon has as many corners as sides, so the totals are simply sides-per-shape multiplied by the number of shapes; a circle contributes none of either.

Enter shape, how many of them. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
