Question

Using a mesuring tape with a least count of 0.1 cm, you measure a package you wish to ship and record the length, width, and height as 12.1 cm, 9.8 cm and 7.6 cm. The sum of the linear dimensions (length plus width plus height ) is often used to calculate the shipping rate. Calculate the following values

            a. Sum of linear dimensions __________ cm

            b. Probable percent error in length

            c. Probable percent error in heigth

            d. Probable percent error in width

            e. Probable error of the sum of linear dimensions ___________ cm

            f. Probable percent error of the sum of linear dimensions

            g. Volume of box ___________ cm3

            h. Probable percent error in volume of box

            i. Probable error in volume of box

Explanation / Answer

part a)

sum=s=l+b+h

part b)

percent error in l=(0.1/l)*100

part c)

% eror in b=(0.1/b)*100

part d)

% error in h=(0.1/h)*100

part e)

error in sum=0.1+0.1+0.1

part f)

% error ins=(0.3/s)*100

part g)

volume=V=lbh

part h)

error in V=0.3

part i)

% error=(0.3/V)*100
