The density of the sample of iron is #"7.8 g/cm"^3#.

Explanation:

#"density"="mass"/"volume"#

The mass is given as #"94 g"#.

The volume can be calculated by multiplying the length, width, and height.

#V=2"cm"xx3"cm"xx2"cm"="12 cm"^3#

Plug the known values into the density formula.

#"density"="94 g"/"12 cm"^3="7.8 g/cm"^3#
