1. Volume Pretest Don’t freak out…it’s not for marks!
You’ll need a piece of looseleaf, and your calculator.
1) What is the VOLUME of a cube with a side length of 5 cm?
2) What is the VOLUME of this shape?
3) How many mm3 is 250 cm3?
4) 𝟏 𝟑 𝒙𝟐=𝟐𝟒𝟑. Solve for x.
5) If the volume of this prism is 3600 m3, what is the unknown measure?
10 m
5 m
3 m
30 m
15 m ?

2. Answers
125 cm3
150 m3
mm3
X = 27
8 m

3. #learning
Today we will explore and convert different units used to measure volume.
So that we can measure space of solids and liquids.
Keys to Success:
I can identify and convert metric units
I can covert units of capacity (mL/L)
I can convert between the two, knowing that 1cm3 = 1mL and 1dm3 = 1L

4. Lesson 8.1: Units of Volume and Capacity

5. Recap of Unit Conversion (don’t write this!)
Ex 1: 150 cm = _______ mm?
You move 1 step to the right, so you just multiply by 10!
150 x 10 = 1500 mm
Ex 2: 150 cm2 = _______ mm2?
150 x 100 = mm2
Can you follow the pattern?
Ex 3: cm3 = ________ mm3?
150 x 1000 = mm3

6. Units of Volume x 1000 x 1000 x 1000 x 1000 x 1000 x 1000 km3 hm3 dam3
dm3
cm3
mm3
÷ 1000
÷ 1000
÷ 1000
÷ 1000
÷ 1000
÷ 1000
Ex 1: dam3 = _______ cm3?
Ex 2: mm3 = _______ dm3?

7. Liquids!
If you are using a recipe that is written using the Metric system, you won’t see “pour mm3 of milk into the flour.” Look at the next pop can, or milk carton, or gas station and you will see units of capacity!

8. 1 mL = __1__ cm3 1 L = 1 dm3 Units of capacity: x 10 x 10 x 10 x 10kL hl
daL L dL cL mL
÷ 10
÷ 10
÷ 10
÷ 10
÷ 10
÷ 10
Converting between the two measurements for volume and capacity
1 mL = __1__ cm3
1 L = 1 dm3

9. Example problems Convert the following to mL 3 cm3 0.05 m3
PRACTICE: Page 108 and 109

10. Example problems Convert the following to mL 3 cm3 0.05 m3
X 1000 x = cm3 = mL
÷ 1000 = cm3 = 4000 mL
