Mass and volume

Mass

Mass= a variable telling you how much 

substance there is in an object

! let op: massa is niet hetzelfde als gewicht !

variable	(symbol)	Unit	(symbol)
mass	m	kilogram	kg

calculations with mass

1 kg = 1000g 

1 mg = 0.001 g

1 ton = 1000 kg

Volume

How much space an object 

takes up

formula: V= l x w x h (rectangular object)

variable	(symbol)	Unit	(symbol)
massa	m	kilogram	kg
volume	V	kubieke centimeter	cm 3

calculations with volume

1 mL = 1 cm3

1 L = 1 dm3

1 dm3 = 1000 cm3

1 m3 = 1000 dm3 = 1000 L

Rectangular objects

Volume of a cylinder

r

h

1 L        = 1 dm³

1 mL    = 1 cm³

V = r² x π x h (cilinder)

Irregularly shaped objects

V = V_end - V_start

V = l x w x h

Calculate the volume of cubes A, C and D.
