Hey there!

To find the density of an object, you must use this formula:
Density=Mass/Volume

Knowing that your mass is 128.3741, the only information you need left would be to find the volume of the cube.

Because the side length of the cube is given, you can multiply the length three times in order to find its volume:
1.25*1.25*1.25
=1.953125

Now that you have your volume and mass, divide the mass by the volume to find the density:
128.3741/1.953125
=65.7275392

Therefore, your density would be 65.7275392 grams per inches cubed.

The density of the metal is 65.73 g/in³

Determination of the volume of the metal

  • Length (L) = 1.25 in
  • Volume (V) =.?

V = L³

V = 1.25³

V = 1.953125 in³

How to determine the density of the metal

Density is defined as the mass of the object per unit volume of the object. Mathematically, it can be expressed as:

Density = mass /volume

With the above formula, we can obtain the density of the metal as follow:

  • Mass = 128.3741 g
  • Volume  = 1.953125 in³
  • Density =?

Density = mass / volume

Density of metal = 128.3741 / 1.953125

Density of metal = 65.73 g/in³
