1. Surface Area and Volume
Rectangular Prisms

2. Vocabulary Three-dimensional figure Rectangular Prism
Has length, width, and height
Rectangular Prism
A three-dimensional figure with two parallel bases that are congruent rectangles.

3. Vocabulary Volume Surface Area Net
The amount of space inside a three-dimensional figure
Measured in cubic units
Surface Area
Covers the surface
Ex: how much cardboard you would need to make a cereal box would be surface area
Net
Two-dimensional patterns of three-dimensional figures

4. Volume
V = lwh
l = length
w = width
h = height
V = volume h w l

5. Surface Area SA = 2lw + 2 lh + 2wh SA = surface area l = length
w = width
h = height h w l

6. Surface Area and Volume
Cylinders

7. Volume
V = 3.14r2h
V = Volume
pi = 3.14
r = radius
h = height
To find the volume of a cylinder, find the area of the circular base and multiply it by the height.

8. Surface Area SA = 2(3.14)r2 + 2(3.14)rh
SA = Surface Area
3.14 = pi
r = radius
h = height
To find the surface area, you find the area of the circular base, multiply it by two, and add the circumference times the height to that number.
