In the given question we need to convert 0.075 meter into centimeter. For this purpose we need to know the relation between meter and centimeter. Then only this problem can be solved and the correct answer reached.
Now we know that
1 meter = 100 centimeter
Then
0.075 meter = [(100/1) * 0.075] centimeter
We know that any number when divided by 1 gives the same number.
So
0.075 meter = (100 * 0.075) centimeter
= (100 * 75/1000) centimeter
= (7500/1000) centimeter
= (75/10) centimeter
= 7.5 centimeter.
So from all the given options the correct answer to the question is 7.5 centimeter.

density = mass /volume
1)mass of rock = 26.0 gram
2)volume of rock = volume of water it has displaced= 25.3-13.12 = 12.18
put the value of mass and volume in first equation and get the density value
