1. The mass of cubic nickel piece has been 1112.5 kg.

   According to the statement

   we have given that the A cubic piece of metal measures 5.00 cm on each edge. if the metal is nickel, whose density is 8.90g/cm^3.

   And we have to find the mass of the cube.

   So, For this purpose, we know that the

   Cube is a regular solid with six square faces.

   The mass and the volume of the cube is

   V = a^3

   Where the edge length of the cubic nickel metal has been, a = 5.00cm

   Substituting the value for the volume (V) of nickel cube:

   V = (5)^3

   V = 125 cm^3

   And

   The volume of cubic metal piece has been found to be 125 cm^3.

   And

   The density has been defined as mass of the substance, per unit volume. The density can be expressed as:

   d = m/v

   The density of a given sample, is 8.90 g/cm^3

   The volume of the given sample, is 125 cm^3.

   So,

   mass = density* volume

   mass = 8.90*125

   Mass = 1112.5 kg

   So, The mass of cubic nickel piece has been 1112.5 kg.
