width*height*length=perimeter of a rectangular prism! :)
it means make same shapes only perimeter
There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
To find the perimeter of two-dimensional shapes, add the lengths of all the sides together. The sum is the perimeter of the figure.
That is called the perimeter; in the case of round shapes such as circles or ellipses, it is usually known as the circumference.
A Triangular Prism A Rectangular Prism An Octogonal Prism (basically 3D Shapes)
Perimeter of base*Length of prism.
circular round shapes that go round and round
Cylinder (circular prism) Cube (square prism) Cuboid (rectangle prism)
A rectangular prism has 6 faces.
Length of prism * perimeter of triangular face.
Some 3D shapes are cones, cubes, pyramids, and cylinders.
