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.
The surface area of a prism is the sum of the areas of each of its sides, plus the two bases. As the number of sides, and their shapes are indeterminate, there is no specific formula. The general formula is (2 x base area) + (perimeter x length)
Length of prism * perimeter of triangular face.
