➷ Use this formula:

density = mass / volume

Rearrange it for mass:

mass = density x volume

Substitute the values in:

mass = 100 x 19.3

Solve:

mass = 1930g

What is the length of a side of a cube with a volume of 512 cm 3
Degger [83]
Volume of the cube is given as 512 cm^3
We also know that
Volume of a cube = (side)^3
Then we can use this formula to find the size of each side of the cube very easily.
Let us assume the length of each side = x
Then
x^3 = 512
     = 8
So the length of each side of the cube is 8 cm. I hope you have got the answer you were looking for. You can crosscheck the answer by multiplying 8 three times. You will get the result as 512. This is the only method to solve this problem.
