A68 g bar of gold is cut into 3 equal pieces. how does the density of each piece compare to the density of the original gold bar?

The density would be same.

Step-by-step explanation:

Here, the mass of the original box = 68 g,

Suppose V be the volume of the original box,

Then, the density of the original box =

After cutting this box into 3 equal pieces,

Mass of each piece =

While, the volume of each piece =

So, the density of each piece = =

Hence, the density would be same.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the answer will be the last one
