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
