Archimedes' principle: an object in water experiences an upward lift equal to the weight of the volume of water being displaced. volume of water displaced = 8000 cm3 weight of water displaced ~ 1 g/cm3 at room temperature and sea level weight of cube in air = 16000 kgf lift ~ 8000 gf = 8 kgf weight of cube in water = 16000 kgf - 8 kgf = 15992 kgf
One can convert mg to kg by dividing milligrams by 1000.
The mean of a collection of identical numbers is always the identical number itself; in this instance, 12.
mean in math mean the average Ex. 12 + 12 =24 now divide that by 2 the answer is 12
Mean = 14 Median = 12 Mode = 12
