①The park is being renovated and greened, and the worker uncle is preparing to do some data measurements. Let’s also participate in them, okay?

②Think about it, what data do you need to know about graphic measurement? What units will be used?

length, area, volume

③What is length? What is area? What is volume?

Length: The distance between two points. Area: The size of the plane.

Volume: The amount of space an object occupies.

In addition to data, measurement also requires units and rates.

(1) Commonly used units of length, area and volume.

Commonly used units of length: kilometers, meters, decimeters, centimeters

Commonly used area units: square kilometers, square meters, square decimeters, square centimeters

Commonly used units of volume: cubic meter, cubic decimeter (liter), cubic centimeter (ml)
