WELCOME TO CAHSEE

Week Four

NOTES- any slide with a green title should be written down in your notebook.

Lesson #7- Measurement and Geometry

2.1

Perimeter, Area, Volume(10 mins)

• Perimeter- the distance around the object.

• Area- the inside of a 2-D shape.

• Volume- if you filled a 3-D shape.

• Surface Area- the covering of a 3-D shape.

18 feet

10 feet

Perimeter = side + side + side + side = 10.5 ft + 18 ft + 10.5 ft + 18 ft = 57 feet
