Answer:

20

Step-by-step explanation:

Since we know that it takes 5lbs. to break a 2-foot longboard, we first want to figure out how many pounds it takes to break a 1foot board.

5/2=2.5

It takes 2.5 lbs to break a 1-foot board.

2.5x8=20

It would take 20lbs to break an 8-foot longboard.

Hope this helps :)
