Surface Area and Volume of Right Pyramids (Year 10A)

LO: To find surface area and volume of right pyramids

Know:

  • the formula for calculating the area of 2-D shapes (triangles, squares, rectangles)
  • the formula for calculating the volume of pyramids
  • the definition of volume and surface area

Understand:

  • That formulas can be used to quickly find the surface area and volume of pyramids

Do:

  • I can find the surface area and volume of right pyramids

Right Pyramid

A right pyramid is a 3-D shape that has the apex (point of the pyramid) directly above the center of the base.

An oblique pyramid is a 3-D shape where the apex doesn’t not line up directly above the center of the base.


Volume of Right Pyramids

To find the volume of a right rectangular pyramid, you need to find the length, width and height then divide by 3.

Surface Area of Pyramid

To find the surface area of right prisms, first find the net of a 3-D shape, then calculate each individual section.
