Because density = Mass/Volume, solving for mass yields density times volume. The volume of a cube with side length of 6.4 cm would be 262.144 cm3. As no units for density were provided, it's impossible to know exactly what is being asked.
D*262.144cm3=M
If density is in kg/cm3, then 4.5 kg/cm3*262.144cm3=M, M=1179.648 kg.
If density is in g/cm3, then 4.5 g/cm3*262.144cm3=M, M=1179.648 g = 1.179648 kg.

64cm 1.4m = 140cm 140cm - 76cm = 64cm
64/7=9.142857142857143
64 cm
A side length would be 64/4 which is 16 16 times 16 is 256
You know our secret, you must be killed.
64cm.
32cm, the radius is half of the diameter
It is: 64/4 = 16 cm
There are 0.64 meters in 64 cm.
8 x 8 = 64cm squared
