The density of an object is given by the mass divided by the
volume: ρ=M/V . If the object is has a volume
of 342.2±21.3 mm^3 and a mass
of 0.21±0.04 kg show how to calculate the density
and its uncertainty using equation 1-7 on paper. Take a picture of
your calcuation and paste it into the spreadsheet to hand in.

2- Uncertainty of simple power of the product of measured quantities m 2 X Af_ A/-= √(MAX) - (^^x)" If f(x,y)=x"y" OR _f(x,y)= then nAy (1-7) n f ΔΕ where m and n may be positive or negative values. The quantity is called the fractional f error which relates the SDOM to the measured value. The quantities f, x, and y in Eq. (1-7) are the average values. Now we are ready to calculate the uncertainty in the area of the paper. Using Eq. (1-7) we find 2 ^^= √(^Z) + (AW)" (1-8)
