To convert from cubic millimeters (mm^3) to cubic decimeters (dm^3), we need to divide by 1,000,000 (since 1 dm^3 = 1,000,000 mm^3).

5 mm^3 = 5/1,000,000 dm^3 = 0.000005 dm^3

6 dm^3 = 6 dm^3

Now, to convert from cubic decimeters (dm^3) to square meters (m^2), we need to multiply by 1 (since 1 dm^3 = 1 m^2).

0.000005 dm^3 = 0.000005 m^2

Therefore, 5 mm^3 is equal to 0.000005 m^2 and 6 dm^3 is equal to 6 m^2.
