Question
(a) To three decimal places, what is the volume of a cube with an edge length of
? (b) If the cube in part (a) is copper and has a mass of
what is the density of copper to two decimal places
Step-by-Step Solution
Verified Answer
Answer
a. The volume of a cube with an edge length of
is
.
b. If a cube having volume is copper and has a mass of
then the density of copper is
.
1Step-by-Step Solution Step 1: Determine the volume of the cube.
The edge length of the cube =
Volume of cube
Hence the volume of the cube is .
2Step 2: Determine the density of copper.
From the above step, we have the volume of the copper cube
We know that
Hence the density of the copper cube is .
