A golden-colored cube is handed to you. The person wants you to buy it for 60 thousand, saying that it is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3g/cm.You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?
Answers
Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u shld not bye it...
Instead u shld call the police for arresting the person...
Answer:
The density of the cube is . The cube is not gold so I will not buy it.
Explanation:
- The mass of the object divided by its volume gives the density of the object.
- We can check the purity of a substance by comparing its density with the density of pure material.
The formula used for density is given by:
where the mass of the object.
object volume.
Step 1:
Given the cube of side .
The volume of the cube,
Density of cube
Step 2:
The gold has a density
So, cube density is less than that of gold.
Hence, the cube is not of gold. I will not buy it.
