mart [117]

For this case the first thing you should do is take into account the following conversion:

1m = 100cm

Therefore, by applying the conversion we have:

(250,000\frac{cm^3}{m^2})((\frac{1}{100})^3\frac{m^3}{cm^3})

Rewriting we have:

(250,000\frac{cm^3}{m^2})(\frac{1}{100^3}\frac{m^3}{cm^3})

(250,000\frac{cm^3}{m^2})(\frac{1}{1,000,000}\frac{m^3}{cm^3}) = 0.25\frac{m^3}{m^2}

Answer:

The rate in m^3/m^2 is:

0.25\frac{m^3}{m^2}
