**Calculating the Volume and Surface Area of a Rectangular Prism**

**Geometry and Measurement: Skills You’ll Need:**

**Surface Area:** The surface area of a rectangular prism is the sum of the areas of all its faces. Since opposite faces are congruent, this formula can be used to find the surface area:

**SA= 2 x area of base + 2 x area of side face+ 2 x area of front face.**

***********************

**Volume:** The volume of a rectangular prism is the space occupied by the prism. One formula for the volume is:

**V = **area of base x height

**Problem Solving Question of the Day**

**Problem Solving Success Criteria:**

- Listen closely and record the problem solving question after watching video twice.
- Assume one of three roles in group: recorder, materials organizer and presenter.
- All group members are engaged and assist in solution of problem solving question.
- Your group’s noise volume does not distract others (Mr. Wass does not have to ask you to quiet down).
- Show your work so that it is easily understood by anyone familiar or unfamiliar with calculating surface area.
- Include a “To Determine” and “Therefore statement.”
- Practice and then clearly present your solution.
- Get the answer right!
