**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**.
