Susan and her friend found a piece of metal which they want to identify. Here is what they figure out so far:
Mass of this metal is 74 g
Volume of this metal is 40 cm3

The given  metal is beryllium.

Explanation:

Given data:

Mass of metal = 74 g

Volume of metal = 40 cm³

Which metal is this = ?

Solution:

First of all we will calculate the density.

it is mass divided by volume.

d = m/v

d = 74 g/40 cm³

d = 1.85 g/cm³

In literature it is given that the density of beryllium is 1.85 g/cm³. Thus given  metal is beryllium.
