when we say

(for example)a,b and c are the dimension of Parallelogram

a=2.267+- 0.002 cm

b=3.376+-0.001 cm

and

c=0.207+-0.001 cm

dose that means that we used equipment to calculat a and another to calculate b and c ?

because i know that delta a or b or c is half of the smallest Grad of the measure equipment

and if they asked for the volume

v=a*b*c (2.267*3.376*0.207)

and the delta v what would bee???

this is not a homework it is for sake of knowledge

thank you :}
