Question

5. An object is a regular, rectangular, solid with dimensions of 2 cm by 3cm by 2cm. It has a mass of 24 g. find its density.

Answer 1

Density, D = 2g/cm^3

Step-by-step explanation:

Given the following data;

Length = 2cm

Width = 3cm

Height = 2cm

Mass = 24g

Density = ?

Volume of a rectangular solid (V) = Length × Weight × Height

Therefore, V = L× W × H

Substituting the values, we have;

`V = 2 *3 * 2 = 12`

V = 12cm

Density can be defined as the ratio of mass to volume i.e mass all over volume.

Mathematically,
`Density = (Mass)/(Volume)`

`D = (M)/(V)`

Substituting the values, we have;

`D = (24)/(12)`

Density, D = 2g/cm^3

Hence, the density of the rectangular solid is 2g/cm^3.
