Surface Areas and Volumes
definition
- Volume: Amount of space occupied by a three-dimensional object is called its volume.
- Capacity: Capacity means the ability of the hollow object to hold substance, i.e., solid, liquid, or gas. It is a measure, that ascertains the amount of space available in a container, that can be filled with matter.
notes
Volume:
-
The measure of this occupied space is called the Volume of the object.
-
The volume of an object is the measure of the space it occupies, and the capacity of an object is the volume of substance its interior can accommodate.
-
It is nothing but space, taken up by the substance which can be solid, liquid, or gas.
-
Hence, the unit of measurement of either of the two is a cubic unit.
-
Both solid and hollow objects have volume.
Capacity:
-
Capacity means the ability of the hollow object to hold substance, i.e., solid, liquid, or gas. It is a measure, that ascertains the amount of space available in a container, that can be filled with matter.
-
Measured in metric units such as liters, gallons, etc.
-
Only hollow objects have the capacity.
-
1 mL = 1 cm3,
1 L = 1000 cm3,
1 m3 = 1000000 cm3 = 1000 L.
