(width)
A unit might be
measured in inches,
feet, centimeters,
etc.
11. How many cubic units is this Cube?
3 x 3 x 3 =
27 cubic units
L W H
V = s3
12. Cylinder
• The cylinder has a radius and a height. Think
of the area of the circle r2 and then to find
the volume multiply the area by the height.
You extruded the circle to give it a third
dimension. Just like the squares and the
rectangle.
14. Example:
Ralph Laureen has a cylindrical water jug. It
has a radius of 6 cm and a height of 25 cm.
