a cubic piece of metal measures 5.00 cm on each edge. if the metal is nickel, whose density is 8.90g/cm cubed, what is the mass of the cube?
that's what I don't understand! :(
The volume of the cube:
5 * 5 * 5 = 125 cubic centimeters
volume = length x width x height and those are given in the problem.
To find the mass of the nickel cube, we need to multiply its volume by its density.
Step 1: Calculate the volume of the cube:
The volume of a cube can be found by cubing the length of one of its sides.
Given that each edge of the cube measures 5.00 cm, the volume is calculated as follows:
Volume = (Edge Length)^3 = (5.00 cm)^3 = 125.00 cm^3
Step 2: Use the density to find the mass:
Density is defined as mass per unit volume. In this case, the density of nickel is 8.90 g/cm^3.
To find the mass, we multiply the volume (125.00 cm^3) by the density (8.90 g/cm^3):
Mass = Volume x Density = 125.00 cm^3 x 8.90 g/cm^3 = 1112.50 g
Therefore, the mass of the nickel cube is 1112.50 grams.
mass=density*volume
figure first the volume of the cube.
