What substance is it?

Answer 1

Answer:

2.7g/cm³

Aluminum

Explanation:

Given parameters:

Mass of the cube  = 72.9g

Unknown:

Density of the cube = ?

Solution:

To solve this problem, we need to find the density of the cube. The mass is given and the dimensions of the solid figure.

Now;

       Density is the mass per unit volume of a substance

     Density  = $\frac{mass}{volume}$  

Volume of the cube  = L³  = 3³   = 27cm³

So;

     Density  = $\frac{72.9}{27}$   = 2.7g/cm³

The body is aluminum because it has a density of  2.7g/cm³
