Each side of a metal cube is measured to be 2.0 cm ±0.20 cm. What is the absolute uncertainty in the calculated volume of the cube?

Answer 1

The relative uncertainty in x^n is n times the relative uncertainty in x.
the relataive uncertainity in the above is 10 percent, so the relative uncertainity in the volume is 30 percent
Volume=8.0+-2.4 cm^3
absolute uncertainity=4.8 cm^3

another way:
high volume-low volume
2.2^3-1.8^3= 4.8cm^3

Answer 2

so bad not efficient

Answer 3

the answer is not 4.8
