Let’s Wrap It Up!

1) After doing this lab, I understand more about:

a.______b.______

c.______d.______

2) To find the ______of a 3D figure, simply find the area of

all the faces of that figure, and ______all of the areas together! It’s just like

finding the area of ______figures! I also know that my answer must

always be written in ______units.

3) Which of the following relate to surface area? Circle all that apply.

a. Wrapping a present

b. Determining how much cardboard is needed to make a box

c. Filling a pool with water

d. Painting a toy box

e. Putting toys inside the toy box

f. Figuring out whether a present fits inside a gift bag

How did you determine which situations applied to surface area?______

______

______

Station 1

Side Length = 3 inches

Formulas:

Area of a Rectangle or Square = lw

Area of a Triangle = ½ bh

Station 2

Triangle Base = 2 inches

Triangle Height = 3 inches

Formulas:

Area of a Rectangle or Square = lw

Area of a Triangle = ½ bh

Station 3

Square Base Length = 2 inches

Height of Prism = 3 ½ inches

Formulas:

Area of a Rectangle or Square = lw

Area of a Triangle = ½ bh

Station 4

Triangle Base = 2 inches

Triangle Height = 3 inches

Height of Prism = 3 inches

Formulas:

Area of a Rectangle or Square = lw

Area of a Triangle = ½ bh

Station 5

Square Base Length = 4 inches

Triangle Height = 3 inches

Formulas:

Area of a Rectangle or Square = lw

Area of a Triangle = ½ bh

Station 6

Begin your Homework

(MSG pages 159, 158, and 161)!

Instructions:

1) Begin with the problems on MSG page 158 and 161. Draw the net for each problem (#3 on page 158 already shows the net). See the back of this sheet for some hints if needed!

2) Fill in the notes on pages 159 and 158, based on what you have learned yesterday and in this lab.

Formulas:

Area of a Rectangle or Square = lw

Area of a Triangle = ½ bh
