1. VOLUME

2. What is Volume?
Volume is the measure of the capacity of a container.
It is the measure of how much a container of a particular shape will hold - liquids, dry substances, etc.

3. *Always measured in units cubed (u3)
VOLUME
VOLUME is the amount of liquid or solid that will FILL a 3-Dimensional object!
*Always measured in units cubed (u3)

4. QUICK DEFINITION
3-Dimensional objects are NOT FLAT.
They have 3 measurements:
Length
Width
Height

5. Cubic Units Volume is measured in cubic units.
Use cubes to fill a rectangular prism such as a box.

6. RECTANGULAR PRISM
The volume of a 3-D object called a RECTANGULAR PRISM, which is a solid figure that has six faces that are all rectangles. Opposite faces are congruent and parallel.

7. A unit might be measured in inches, feet, centimeters, etc.
One Cubic Unit
1 unit (length)
A unit might be measured in inches, feet, centimeters, etc.
1 unit (height)
1 unit (width)

8. How many cubic units is this rectangle?
What did you find?
Yes, it is 8 cubic units!

9. The formula for finding the volume of a rectangle is ….
What’s the formula?
The formula for finding the volume of a rectangle is ….
L x W x H = Volume
This means we take the length times the width, then multiply that by the height.

10. Let’s try it!
L = 3
H = 3
W = 2
3 x 3 x 2 = 18 cubic units

11. Find the volume of this one!
What did you find?
4 x 2 x 3 = 24 cubic units

12. FIND THE VOLUME OF THIS RECTANGULAR PRISM:
3 mm
2 mm
12 mm

13. Let’s practice some problems and solving them.
A cereal box has a length of 8 inches, a width of 1.75 inches, and a height of inches. How much cereal will the box hold?

14. Alexis’s bathroom has a tub in the shape of a rectangular prism with a length of 1.5 meters, a width of 0.5 meter, and a height of 0.4 meter. How many cubic meters of water can it hold?

15. Now let’s try a more challenging problem.

16. Be Careful. You must convert 3 feet to inches
Be Careful! You must convert 3 feet to inches. Subtract and then convert back to feet.

17. Length x Width x Height 12 x 2 x 2 ½ 24 x 2 ½ 60
Length = 12 feet
Width = 2 feet
Height = 30 inches or 2 ½ feet
Length x Width x Height 12 x 2 x 2 ½ 24 x 2 ½ 60 A

18. BINGO Let’s Practice finding Volume
