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

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

4. RECTANGULAR PRISM Today we found 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.

5. VOLUME OF A RECTANGULAR PRISM So, what if we wanted to find the volume of this classroom?

6. FORMULA Luckily, we have a formula for that! Volume = length × width × height

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

8. FIND THE VOLUME OF THIS RECTANGULAR PRISM: 10 in 3 in 4 in

9. FIND THE VOLUME OF THIS RECTANGULAR PRISM: 5 cm
