Here is the base of a prism.​​​​​​

1. If the height of the prism is 5 cm, what is its surface area? What is its volume?
2. If the height of the prism is 10 cm, what is its surface area? What is its volume?
3. When the height doubled, what was the percent increase for the surface area? For the volume?

Select all the situations where knowing the volume of an object would be more useful than knowing its surface area.

Han draws a triangle with a \(50^\circ\) angle, a \(40^\circ\) angle, and a side of length 4 cm as shown. Can you draw a different triangle with the same conditions?
