# Solve problems involving surface area and volume of right pyramids, right cones, spheres and related composite solids (VCMMG365)

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.
