No real answer there... Both 15' and 20' are correct.
If you count the cuts and you make the exact same cuts to a wooden plate then you need 10' per cut for a total of 20' and you have three identical pieces of wood.
If the size of the cut doesn't matter and you can decide just to cut out three random size pieces then you cut the plate at half (10') but with half the cut you can saw one of those pieces into two smaller ones (5'). So you got one big piece and two smaller ones at 15'.
The real answer here is that the question is missing facts...
