# Copy of DIY Maths: Surface area of cubes, cuboids and triangular prisms

## SURFACE AREA OF CUBES, CUBOIDS AND TRIANGULAR PRISMS

In this module, you can study how to find the of a, a (or rectangular prism) and a triangular

The above video shows a teacher explaining how to find the surface area of a rectangular prism.

The video above shows how to find the surface area and volume of a triangular prism. It's a very good explanation, but you need to know the Pythagorean theorem to understand it fully.

The video above is a visual explanation about how people figured out the formulas for the surface area of rectangular and triangular prisms and cylinders.

## Did you know?

The surface area formulae for all prisms and cylinders are the same.  They are all (two x the area of the base) plus (the perimeter of the base x the height of the object).

Even though a prism is a three-dimensional object, its surface area is two-dimensional.
