A bookshelf is 75 cm wide. How many decimeters is this? How many meters is this?

12. 75 cm = 7.5 dm 75 cm = .75 m

13. Volume The amount of space occupied by an object.
Length x Width x Height
Units = cubic….
Cubic centimeters = cm3
Cubic meters = m3
Liquid volume
Liter

14. Derived Units Units that are made by combining other SI units
Meter x Meter x Meter = M3

15. Mass The amount of matter in an object. SI unit = kg
Use a balance to measure mass.

16. Density The mass per unit volume of a material.
Density is a derived unit.
Mass/volume
g/cm3

17. Time
The interval between two events
SI unit = seconds (s)
