    I know it is 1 in ^3 = 16.4 cm ^3

    but if you want 4 sig figs, the we should use

    1 in ^3 = 16.39 cm ^3

    we know that (1 ft) = (12 in)

    cubing both sides gives us

    (1 ft^3) = (1728 in^3)

    so 55.53FT^3 times (1728 in^3) / (1 ft^3) times (16.387 cm ^3) / (1 in ^3 ) = 1,572,428 cm^3

    which rounded to 4 sig figs is

    1.572 X 10^6 cm^3

    you can find conversion factors by googling

    i.e "convert 1cubic foot into cubic inches"

    google gives the answer: "1 (cubic foot) = 1728 cubic inches"

    you can also check any conversion answer at

    it says that

    55.53 cubic foot = 1 572 434.491 3 cubic centimeter
