A lumberjack cuts 7 pieces of equal length from a log. What is the change in the log's length after 7 cuts

Question

the pieces of cut log are 2 and 1/4 ft

Answer 1

2 1/4 = 2.25 feet

(2.25)x7^7 = 2.25 x 823543 = 1,852,971.75 feet = log's initial length= about 350 miles which is impossible given even the Redwoods in California

the log's length doesn't change, it just gets cut up into 49 pieces, all which sum to the same length

UNLESS you meant 7 cuts to be the 6 cuts in a one time cuts of the log into 7 pieces. Then 2 1/4 x 7 = 15 3/4 feet

cut it once you get 2 pieces, but you might call the 2 pieces 2 cuts. so 7 cuts means cutting the log in 6 different places

15 3/4 - 2 1/4 = 13 1/2 foot difference in length
