- 2. Volume Volume is the amount of matter that can fit into a 3d object It is used for aquariums and pools and also packaging You convert one unit to the other by multiplying from m^3 to cm^3 multiply by 1000000 or the other way dividing by 1000000. Multiply 1000 from cm^3 to mm^3 and the other way divide by 1000
- 3. Examples 1m^3*1000000=1000000cm^3 1000000cm^3/1000000=1m^3 1cm^3*1000=1000mm^3 1000mm^3/1000=1cm^3 1m^3*1000000000=1000000000mm^3 1000000000mm^3/1000000000=1m^3
- 4. prisms To find the volume of prisms you multiply the length times width times height To find the volume of a prism with a cross section you find the area of the base then that times the height
- 5. Examples
- 6. Capacity Capacity is the amount of water a 3d object can hold We use capacity for fish bowls, aquariums, and reservoirs You times 1000 to convert to lower unit and divide by 1000 to convert to a higher unit 1ml is 1cm^3, 1000cm^3 is 1l, 1m^3 is 1kl
- 7. Examples 1kl*1000=1000l 1000l/1000=1kl 1l*1000=1000ml 1000ml/1000=1l 1kl*1000000=1000000ml 1000000ml/1000000=1kl 3cm^3=3ml 1000cm^3=1l 1m^3=1kl
- 8. Mass Mass is the amount of matter it has We use mass for weight, for cooking and for stars and planets You convert mass by multiplying and dividing by 1000
- 9. Examples 1Kg*1000=1000g 1000g/1000=1kg 1g*1000=1000mg 1000mg/100=1g 1kg*1000000=1000000mg 10000000mg/1000000=1kg
- 10. Time To convert time you divide by 60 to get seconds and minutes and to get hours you divide by 24 then divide by 7 to get days and by 52 to get weeks We use time ones because in one place the sun will be setting and in other places the sun will be rising
- 11. Examples 1min*60=60 sec 60sec/60=1min 1h*60=60mins 60mins/60=1h 1d*24=24h 24h/24=1d 1w*7=7d 7d/7=1w 1y*52=52w 52w/52=1y
