Calculate the density of a regular solid that measures 2cm x 3cm x 5cm and has a mass of 10g.?

How will I set this problem up? 30cm/10g.

No, your calculation is incorrect, it's the other way around.

Density = Mass/Volume = 10g ÷ (2cm x 3cm x 5cm)
= 10g/30cm³ (cc).
= 0.333g/cc

Volume = 2 x 3 x 5 = 30 cc

Mass = 10 g

Density = Mass / Volume = 10 / 30 = 1 / 3

= 0.33 g / cc approx.

D=m/V

you know the mass is 10 g

find the volume. If we assume it is rectangular then the volume is 2cmx3cmx5cm=30cm^3

Thus D=10g/30cm^3

Your answer of 30cm/10g can not be correct because density is MASS/VOLUME. You have volume/mass.
