In preparation for the zombie apocalypse, you decide to cut enough wood to heat your house for the entire winter. You may end up deforesting the area around your house, but at least you will be able to see the zombies coming for you!

Your small, well-insulated home will require 25,000BTUs per hour for 3 months to get through the winter. A cord of the wood will yield about 18 million BTUs.

How much wood do you need to cut to provide enough wood to heat your house for the winter?


250,000 cords of wood


54 cords of wood


18 cords of wood


3 cords of wood
