Question

A block measures (3cm x 2cm x 4cm). The mass is. What is 48g. What is the density of the object?

A. 24g/cm^3

B. 0.5g/cm^3

C. 2 g/cm^3

D. 72 g/cm^3

Answer 1

Answer:

2g/cm³

Explanation:

Given parameters:

Dimension of the block = 3cm x 2cm x 4cm

    Volume of block  = 3cm x 2cm x 4cm  = 24cm³

Mass = 48g

Unknown:

Density of the object = ?

Solution:

Density is the mass per unit volume of a substance. It is expressed as;

  Density  = $\frac{mass}{volume}$  

So;

  Density  = $\frac{48}{24}$   = 2g/cm³
