The surface area of a 3D shape is equal to the sum of the areas of all the faces (sides) of that shape. A helpful way to think about it is:We can also think about surface area in terms of gifts! The surface area is like the minimum amount of wrapping paper we need to prep a gift for its surprise reveal. 🤩If we were to unwrap a gift, the amount of wrapping would be equal to the surface area of the object it was covering.When we “unwrap” a 3D shape, we get what we call a net. A surface area net shows us the different 2D shapes that make up the faces of the 3D shape.When working with pyramids, cylinders, and cones, you may also be asked to find the lateral surface area.Check out our or explore our and sections to learn more about how to find the surface area of square pyramids and test your understanding.

We can then find the area of each face and then add them all together to find the total surface area.

### What is lateral surface area?

Lateral surface area is simply the total surface area of an object minus the area of its base(s).
