$707.92 cm^3$

Work Step by Step

$(\frac{.02500ft^3}{1})\times(\frac{28316.8 cm^3}{1 ft^3})= 707.92 cm^3$ In this unit conversion, the unit $ft^3$ is on the top and bottom of a fraction, thus making this unit cancel out, leaving the desired unit $cm^3$. Also, the given number $.02500ft^3$ is multiplied by $(\frac{28316.8 cm^3}{1 ft^3})$. This step is legal because $28316.8 cm^3$ equal $1 ft^3$, meaning that multiplying by this fraction is like multiplying by one, for the numerator and denominator of the fraction are equal. Hence, this leaves the answer in the desired unit, $cm^3$.
