Question

How do you find the perimeter of a prism

Answer 1

triangle = a + b + c where a, b and c are the three lengths of the triangle.

rectangle: 2l + 2w where l is the length of the rectangle and w is the width.

Answer 2

Perimeter of triangle = a + b + c where a, b and c are the three lengths of the triangle.

This would be the perimeter of a rectangular prism formula:

Perimeter of rectangle: 2l + 2w where l is the length of the rectangle and w is the width.

Apply standard perimeter calculations to the base shape of the prism, and that gives you the perimeter.
