Final answer:
Perimeter is the distance around a figure, area is the space inside a figure, and volume is the space inside a three-dimensional object.
Step-by-step explanation:
The concept of perimeter is the distance around the exterior of a two-dimensional figure and is measured in linear units. For example, in a square with sides of length 7 cm, the perimeter would be 4 * 7 cm = 28 cm.
The concept of area is the amount of space inside a two-dimensional figure and is measured in square units. For example, the area of a rectangle with length 6 cm and width 4 cm would be 6 cm * 4 cm = 24 cm².
The concept of volume is the amount of space inside a three-dimensional object and is measured in cubic units. For example, the volume of a rectangular prism with length 10 m, width 10 dm, and height 7 cm would be 10 m * 10 dm * 7 cm = 7000 cm³.
