Based on the calculations, the height of this object is equal to 6.01 cm.

Density can be defined as a ratio of mass to the volume of a physical object such as a metal, gray cube, or tennis ball. Mathematically, the density of a physical object can be calculated by using this formula:

Density = M/V

Where:

Making volume the subject of formula, we have:

Volume = Mass/Density

Substituting the given parameters into the formula, we have;

Volume = 616.6/2.4

Volume = 256.92 cm³.

Now, we can determine the height of this physical object  by using this formula:

Volume = Length × Width × Height

256.92 = 9.5 × 4.5 × Height

256.92 = 42.75 × Height

Height = 256.92/42.75

Height = 6.01 cm.
