Since both the measurements are rounded, let’s first find out the smallest possible values they could have had before rounding. This would be finding the smallest possible number, which when rounded, gives us the numbers mentioned above. 0.9mm -> 0.85mm 0.13mm -> 0.125mm Using these values, we need to find two things, the total thickness of the pages and the total thickness of the covers. Adding these two will give us the answer. 0.85 x 2 = 1.7mm 0.125 x 400 = 50mm Adding these gives us our answer: 1.7 + 50 = 51.7mm
