Density = 2.7g/cm3
mass =8.1grams
from density =(mass)/volume
we can determine the volume of aluminium by simply changing the subject of the subject of the formula from density to volume
so we have
volume=mass/density
=(8.1grams)/(2.7g/cm3)
=3cm3
The dimensions needed for this is <span>55 cm x 100 cm x 80 cm.</span>
It will decrease
When the temperature increased, the rate will decrease
Volume=400cm^3 = 0.0004m3
Density = mass / volume
(7.8*10^3 ) * 0.0004 = mass
Mass = 3.12 kg
Weight = mass * gravitational field strength
W = 3.12* 10
= 312 N
