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.

Answer is 1480g Do the math. Someone already gave the formula. The cm cancels out after multiplying. Note: you have to cube the 5.5cm
