Each box had 100 blocks in it.
-- 1/5 of the blocks in one box = 100/5 = 20 blocks.
-- 1/5 of the blocks in the other box = 100/5 = 20 blocks.
-- Total number of blocks used = (20 + 20) = 40 blocks.
Ben used a total of 40 blocks to build the tower, with 20 blocks coming from each of the two boxes. This was calculated by taking 1/5 of the blocks from each box, which contained 100 blocks each. Thus, he used 20 blocks from each box, resulting in 40 blocks altogether.
