Units of Measure

100

temperature in USA

fahrenheit

200

temperature in other countries besides USA

celsius

300

measure for mass

g, kg

400

measure for volume of a liquid

mL, L

500

measure for the volume of a solid

cm3

Find the volume

100

L=5cm  W=7cm  H=2cm

5x7x2 = 70 cm3

200

L= 4in  W= 8in  H= 8in

4x8x8= 256 in3

300

L=10cm  W=10cm  H=11cm

10x10x11= 1100 cm3

400

L= 9in  W=11in  H= 6in

9x11x6= 594in3

500

L= 22cm   W= 13cm  H=9cm

22x13x9 = 2574cm3

Find the Density

100

m= 96g  v=8cm3

96 divided by 8 = 12g/cm3

200

m=121g   v= 11cm3

121/11 = 11g/cm3

300

m=54.5g   v=5cm3

54.5/5=  10.9g/cm3

400

m=642g  v=12cm3

642/12= 53.5g/cm3

500

m=1125g    v= 9cm3

1125/9 = 125g/cm3

What is it?

100

1

300

the mass of a small paper clip?

1g

400

1 mL is equal to ______ cm3?

1 cm3

500
