When a part dimension is specified as "0.236 ± 0.003 cm",it would mean that the target,or ideal value,is 0.236 centimeters,and that the allowable variation is 0.003 centimeters from the target.This means that the tolerance is:
A)-0.0003 cm.
B)0.006 cm.
C)0.003 cm.
D)-0.0006 cm.

The tolerance is the allowable deviation from the target value. In this case, the allowable deviation is 0.003 cm. Therefore, the tolerance is +0.003/-0.003 cm or a total range of 0.006 cm (0.003 cm above and below the target value). Therefore, the correct answer is B (0.006 cm).
