A prism is a solid that has two parallel faces which are congruent polygons at both ends. These faces form the bases of the prism. A prism is named after the shape of its base.
The other faces are in the shape of parallelograms. They are called lateral faces.
A right prism is a prism that has its bases perpendicular to its lateral surfaces. If the bases are not perpendicular to its lateral bases then it is called an oblique prism.
When we cut a prism parallel to the base, we get a cross section of a prism. The cross section has the same size and shape as the base.
What is a prism and distinguishes between a right prism and an oblique prism?
How to label the parts of a prism and how to distinguish between an oblique and a right prism?
Volume of a Prism
The volume of a right prism is given by the formula:
Volume = Area of base × height = Ah
where A is the area of the base and h is the height or length of the prism.
Worksheet to calculate volume of prisms and pyramids.
Example: Find the volume of the following right prism.
Solution: Volume = Ah = 25 cm 2 × 9 cm = 225 cm 3
Example: Find the volume of the following right prism
Solution: First, we need to calculate the area of the triangular base.
We would need to use Pythagorean theorem to calculate the height of the triangle.
h 2 + 3 2 = 5 2
Volume of prism = Ah = 12 cm 2 × 8 cm = 96 cm 3
How to find the volume of a rectangular and a triangular prism? Step 1: Find the area of the base. Step 2: Multiply the area of the base times the height.
How to find the volume of any prism, right or oblique using a general formula?

Problem solving with volumes of prisms
A problem-solving activity using volumes of prisms and cylinders, plus constructing and solving simple equations.
Students are shown prisms and a cylinder with measurements given either numerically or as unknowns x, y and z.
They must use the information to form and solve simple equations to find all the unknowns as well as the radius of the cylinder.
Students can then create their own prism with the same volume to go in the empty box.
