Volume of Right Prisms with Polygon Faces
Right Prisms
• Any prism that has two polygon faces that are parallel is considered a right prism. They are named by the polygon that makes up the face.
• Rectangular Prisms have two rectangles as the polygon that makes the base
• Triangular Prisms have two triangles as the polygon that makes the base.
Finding the Volume of Prisms
• To find the volume of any right prism, find the area of the face and multiply by the depth.
Triangular Prisms
Area of the triangular face : = 6cm²
Area of the base multiplied by depth = volume
6cm² · 11cm = 66cm³
Sometimes the Height or Base is Not Given
• You may need to use the Pythagorean Theorem to find the missing value
Trapezoidal Prism
Pentagonal Prism
