Assuming that this is a rectangular prism, you just multiply length times width.

You will need to find the surface area of each face and add them together.


How do you calculate the total surface area of prism?

Find the area of each face separately and then add them together for the total surface area.


Calculate surface area of a prism?

To find the SA of any prism, find the area of each face. (*Note: Depending on the shape of the face, there might be different formulas. Area of Square=length x length Area of Triangle=base x height divided by 2 Area of Trapezoid=A1+A2 (divide the trapezoid into two triangles and find the area of each triangle, then add them) ) After you find the areas of all the faces of the prism, add all the areas to get the SA.


What is the suface area of a rectangular prism?

What is the formula for the lateral area of a triangular prism?

Length of prism * perimeter of triangular face.


How do find the surface area of a triangular prism?

Surface area of the triangle x the length of the prism.


How do you find the lateral area of a triangular prism?

The lateral area of a triangular prism is found by computing the perimeter of the triangular base (sum of the three sides) and multiplying it by the height of the prism. If the triangular base has sides of length s1, s2, and s3, and the height of the prism is h, then each lateral face of the prism would be a rectangle. The area of one face of the prism would be (s1 x h), the area of the second face of the prism would be (s2 x h), and the area of the third face of the prism would be (s3 x h). So the three lateral faces would have a total area of (s1 x h) + (s2 x h) + (s3 x h), or equivalently (s1 + s2 + s3) x h; i.e., (the perimeter of the triangular base) x (the height of the prism).


How do you fin the volume of any prism?

Find the surface area of the top or bottom face and multiply that by the depth of the prism. For example, a triangular prism would have a volume of (1/2 * base * height) * (depth)


How do you find the area of a pentagonal prism?

A prism is a 3-dimensional figure, which has a volume, so I presume you mean surface area. The simple answer is you find the area of each face (both pentagons and all 5 parallelograms), and then add them together. If you don't know how to find the area of one or more of the faces, that is a separate question.


How do you find the volume of a hexogonal prism?

Find the area of one end of the prism, then multiply it by the length of the prism.
