12 Suppose that you determine the height of 50 objects by me

1.2 Suppose that you determine the height of 50 objects by measuring the first, and then stacking the second on top of the first and measuring their com- bined height, stacking the third on top of the first two and measuring their

Solution

Here first measurement is the height of the first object.

Second measurement is the height of the first and second

and third the height of first, second and third.

In other words, the readings of nth gives the weight of first n objects, 0<=n<=50

i.e. cumulative heights are recorded here each time and the last one will be the total of all heights.
