Finding the surface area of a rectangular prism

May 31, 2020



Learn how to find the volume and the surface area of a prism. A prism is a 3-dimensional object having congruent polygons as its bases and the bases are joined by a set of paralellograms. A prism derives its name from the shape of its base, i.e. a prism with triangles as its bases is called a triangular prism while a prism with square bases is called square prism, etc.

The volume of a prism is given by the area of its base multiplied by its height (the distance between its bases). While the total surface area of a prism is given by the sum of the areas of all the plane shapes making up the prism.

  • taking a geo test rn. rectangular prisms and area stumped me. im not gonna pass this test. thanks anyways.

    EDIT: im reviewing my notes, and it says to get surface area I have to multiply length times width times height. So why add?
