Interesting math problems and answers are filled with 100 boxes. The number of each box is different, and the boxes are not empty. So how many cups do you need at least?
The number of cups in the first box is 1, 2, 3, 4, ... 99, 100.

So at least one drink.

1+2+3+4+……+99+ 100

=( 1+ 100)× 100÷2

= 10 1×50

=5050 (pieces)
