Cut out the cards and match each word to its meaning. Or draw a line to connect them.
| Face | A flat side of a solid figure. |
| Net | A flat pattern that folds into a solid. |
| Surface area | The total area of all the faces of a solid. |
| Rectangular prism | A box-shaped solid with 6 rectangular faces. |
A student made this mistake:
Mistake: Forgetting to double, so only 3 faces are counted.
1. What did the student do wrong?
2. Fix it. Show the correct work.
Hint for the fix: Every face has a matching opposite face, so multiply the three areas by 2.
1. Find the surface area of a cube with side 2.
2. Find the surface area of a prism 2 by 1 by 1.
Find a real box at home, measure it, and find its surface area.
Show your work and explain your reasoning.
Keep separate from students.
