Density = (mass)/(volume)
170 mm = 17 cm
25.4 mm = 2.54 cm
Volume = (17 x 2.54 x 2.54) = 109.6772 cm3
Density = 8.2/109.6772 = 0.0748gram/cm3
This is a very intriguing density for a rectangular rod ... only 7.5% as dense
as water, 2.8% as dense as aluminum, 14.1% as dense as lithium, the lightest
metal, and only 63 times as dense as room-temp sea-level air. We're suspicious
of the figure given for mass, but we stand behind our math.
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
You divide its mass by its volume.
It is the mass of the block divided by its volume.
Volume x Density . . . yes
You multiply its density by its volume.
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.

You divide its mass by its volume.
It is the mass of the block divided by its volume.
Volume x Density . . . yes
You multiply its density by its volume.
You need its mass and volume.
on a balance
W = Volume x weight density
Volume
You measure its length, breath, height and mass. Then Density = Mass/(Length*Breadth*Mass) in the appropriate units.
Density = Mass/Volume = 850/(9*7*12) = 1.1243 grams per cm3
