You need to find the area of each of its faces and add them together. An icosahedron may or may not have parallel faces. For example, an icosahedron, in the form of a pyramid with a 19-gon base will have no parallel faces.

When was the surface area formula developed for the triagular prism?

A prism is a polyhedron with two parallel bases bounded by congruent polygons and with lateral faces bounded by parallelograms that connect the corresponding sides of the bases. The height of a prism is any perpendicular line drawn from a point on one base to the other base. If the the bases' shape of a prism is a triangle, we call it a triangular prism (it has 3 faces). The surface area is the sum of the bases' area and the faces' area (lateral area).


Is the surface area of the prism is the sum of the area of the base and lateral faces of the prism?

No, there are TWO bases.

Yes, it must be.


The definition of lateral area?

The lateral area of a three-dimensional object, such as a prism or cylinder, refers to the combined area of all sides excluding the bases. It is calculated by finding the sum of the areas of all the lateral faces of the object.


What is the lateral and surface area of a right prism?

The lateral area of a prism is the sum of the areas of all the lateral faces. A lateral face is not a base. The surface area is the total area of all faces.Lateral Area: The lateral area of a right prism with base perimeter P and height h is L=Ph.Surface Area: The surface area of a right prism with lateral area L and base area is B is S = L + 2B, or S = Ph + 2B.


What are the properties of heptagonal prism?

A heptagonal prism is a three-dimensional geometric shape with two parallel heptagonal bases and seven rectangular lateral faces. Its properties include having 14 edges, 10 vertices, and 7 faces. The lateral faces are perpendicular to the bases, and the height of the prism is the distance between the two heptagonal bases. The volume can be calculated by multiplying the area of the heptagonal base by the height of the prism.
