1. *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)

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

3. 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.

4. Formula for the Volume of a Rectangular Prism
Volume = length × width × height

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

6. 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?

7. 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?

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

9. 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.

10. 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

11. BINGO Let’s Practice finding Volume
