61.2 ml

12. What is the volume shown?

13. What is the volume shown?
37.5 mL

14. B. Measuring the volume of solids

15. a. Measuring Volume of Rectangular solids
measure with a ruler the length (L), width (W) and height (H) of the object.
multiply the 3 numbers together.
The product is the volume of the object.
unit of measure would be mm3, cm3, m3, etc.

16. b. Measuring Volume of Irregular Objects aka The Displacement Method

17. Volume By Displacement
Fill the graduated cylinder at least halfway with water.
Record the volume of the water.
Drop the object into the water without splashing.

18. Record the volume of the water and the object together.
Subtract the volume of the water from the volume of the water and object. This is the volume of the object.
Remember- Convert liquid volume units (ml) to solid volume units (cm3)

19. Today’s Directions
Find the volume of the rectangle by measuring the length, width, and height with a ruler and then multiplying.
Find the volume of the rectangle by using the displacement method.
Find the volume of the glass bead by using the displacement method.
Don’t forget the correct units of measure.
