volume=length times width times height this should be easy
a. the volume of a box is 2.5 times 1 times 1 or 2.5 cubic meters
b. number of boxes times volume per box=volume of container number of boxes=volumecontainer/volumebox find volumecontianer volumecontainer=5 times 2 times 3=30 cubic meters
number of boxes=30/2.5 number of boxes=12 12 boxes needed to fill container
c. box 1m=100cm 1m by 1m by 2.5m convert so (times everybody by 100) 100cm by 100cm by 250cm multiply 2,500,000 cubic centimeters
