Surface Area of Solids

Submit 1 per group. 
Work together to solve the following surface area questions.

Think about the formulas we have learned so far about area of 2D shapes and how 3D shapes are created using 2D shapes. You can also use your MCAS reference formulas sheet to help you.

**You will be able to submit and check if your solutions are correct for the fill-in responses. If you did not get the correct solution, you can re-attempt your responses until the end of class. The show your work responses will be graded later, based on the work shown.**

The surface area of a solid object is a measure of the total area that the surface of the object occupies. 
Think about a net covering the shape, how big of an area would the net need to be to cover the entire surface? 
Can you break down the shape into other shapes to help you solve the total area?
