# 6th Grade Math - Surface Area

Now when we have three-dimensional objects, we can talk about more than just the volume, which is the amount of content inside. We've covered how to do that all week so far. Now let's talk about how much area there is along its surface. That is called the surface area.

Surface area is the sum of all the areas of all the shapes that cover the surface of an object. Some shapes, such as a cube, are fairly simple to calculate the surface area of versus a shape like a cylinder that involves a little more math to solve.

Thankfully, Professor Burger makes this easier with his demonstrations in today's free 6th grade math video. You'll get some great visuals that will not only help you understand the concept but be able to easily apply this knowledge whenever you need. Whether it's planning for how much paint you need to cover a wall or how much tile to buy before laying a new floor, there is a great deal of real world uses for surface area!

Today's video has 3 separate lectures that will provide a good foundation in surface area.

And don't forget to come back tomorrow for the worksheet covering all the videos we've watched this week!
