Volume of carton

  1. Aug 27, 2009 #1
    1. The problem statement, all variables and given/known data
    What is the volume of a carton if tis base has a width of 35.5 cm and a length of 27.23cm? The height of the carton is 54 cm.


    2. Relevant equations

    v=bxh

    3. The attempt at a solution
    35.5x54=1917

    im pretty sure volume is base x height but i dont know if with the length i have to do something more or if thats just there to trick me or what?

    Also an airplane travels at 950 km/h. how long does it take it to travel 1.00 km?..

    Area=base*length

    but volume=base*length*height'

    for the second question:
    here is a hint.
    if something moves at 2km/h

    then in it travels 2km in 1 hour

    so as for question numer 1 it would be 35.5x27.23x54 which equals 52199.91 and rounded to the appropriate number of sig figs it would be 52x10(-3) correct?

    as for question number 2 i understand that concept but its asking how long would it take for it to go 1 km..i tried dividing it by 3600 (seconds in an hour) yet i dont get the answer which is 3.8 according to the back of the book. and im a moron i just figured it out lol 3600/950 thanks a ton

    Question 1 is good.

    If I travel 2km in 1h and you want to know how long it takes me to travel 10km.

    so

    I travel 2km in 1h
    thus for 1km I'd take 1/2h

    in 10km I'd take (1/2*10)h=5h
