Question

The properties of a rectangular prism are listed below: Mass = 120 g Length = 3 cm Width = 2 cm Height = 1 cm What is the density of the rectangular prism? 10 g/cm3 20 g/cm3 360 g/cm3 720 g/cm3

Answer 1

The correct option is:  20 g/cm³

Explanation

Dimensions of the rectangular prism are:  Length = 3 cm, Width = 2 cm and Height = 1 cm

So, the Volume of the prism $= length*width*height=(3*2*1)cm^3 = 6 cm^3$

Now the mass of the prism is given as 120 g

We know that,  $Density = \frac{Mass}{Volume}$

So, the density of the rectangular prism $= \frac{120}{6}g/cm^3 = 20 g/cm^3$
