1. Surface Area and Volume
Vocabulary & Formulas

2. Prism
Definition:
A three-dimensional solid that has two congruent and parallel faces that are polygons. The remaining faces are rectangles. Prisms are named by their faces.

3. Rectangular Prism Definition:
A three-dimensional solid that has two congruent and parallel faces that are rectangles. The remaining faces are rectangles.

4. Cube
Definition:
A rectangular prism in which all faces are congruent squares.

5. Surface Area Definition:
The sum of the areas of all of the faces of a three-dimensional figure.
Ex. How much construction paper will I need to fit on the outside of the shape?

6. Volume
Definition:
The measure in cubic units of the interior of a solid figure; or the space enclosed by a solid figure.
Ex. How much sand will it hold?

7. Surface Area of a Rectangular Prism
Ex:
How much construction paper would I need to fit on the outside of a particular rectangular prism?
Formula:
S.A. = 2LW + 2Lh + 2Wh

8. Surface Area of a Cube Ex:
How much construction paper would I need to fit on the outside of a particular cube?
Formula:
S.A. = 6s2

9. Volume of a Rectangular Prism
Ex:
How much sand would I need to fill the inside of a particular rectangular prism?
Formula:
V = L*W*h

10. Volume of a Cube
Ex:
