The Surface Area of a Prism calculator computes the surface area of a prism (see graphic) based on the dimensions of the triangular side and the length.

INSTRUCTIONS:  Choose units and enter the following:

• (b) This is the base of the triangular side.
• (h) This is the height of the triangular side.
• (l) This is the length of the prism

Prism Surface Area: The calculator returns the volume (A) in square centimeters.   However, this can be automatically converted to other units via the pull-down menu.

The Math / Science

The formula for the surface area of a triangular prism is:

`TSA =   b•h + b•l + 2•l•sqrt((b/2)^2 + h^2)`

where:

• TSA is the total surface area of the triangular prism
• b is the base
• h is the height
• l is the length
