1) A box has dimensions: 1 = 10 cm; x = 5 cm; h = 2.5 cm determined by a mm ruler. Calculate the volume of the box its absolute uncertainty.

2. A micrometre screw gauge is used to measure the diameter of a steel ball bearing which was found to be 4.460.01 mm. Calculate the volume of the ball-bearing in units of mm and its percentage error.
