Right Prism Surface Area Calculator

Posted by Dinesh on

Use the simple geometry calculator to calculate the surface area of a right prism online.

Geometry Prisms - Definitions

  • A Prism is a polyhedron with two congruent polygonal faces that lie in parallel planes.
  • The Bases are the parallel polygonal faces.
  • The Lateral Faces are the faces that are not bases.
  • The Lateral Edges are the edges between the lateral faces.
  • The Slant Height is the length of a lateral edge. Note that all lateral edges are the same length.
  • The Height is the perpendicular length between the bases.
  • A Right Prism is one in which the angles between the bases and the lateral edges are right angles. Note that in a right prism, the height and the slant height are the same.
  • An Oblique Prism is one that is not a right prism.
  • The Surface Area of a prism is the sum of the areas of all its faces.
  • The Lateral Area of a prism is the sum of the areas of its lateral faces.

Surface Area of a Right Prism Calculation


SArp = P×h + 2B

P - the perimeter of the base
h - the height of the prism
B - the area of the base
SArp - Right prism surface area
