• It is the space occupied by a substance.
• It is the measure of how much a container of a particular shape will hold - liquids, dry substances, etc.
•Volume is measured in cubic units.
One Cubic Unit
1 unit
(length)
1 unit
(height)
1 unit
(width)
A unit might be
measured in inches,
feet, centimeters,
etc.
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.
Example:
Ralph Laureen has a cylindrical water jug. Ithas a radius of 6 cm and a height of 25 cm.How much water will fit in the jug?
Answer: 2826 𝑐𝑚3
