135,000 ft is what you’re working with okay so what you have to do is get the total which is 135,000 ft. Then next you divide by what space you need for one FE. That is 6,000 ft. So next you DIVIDE. so 135,000/6,000= 22.5 but you need to round it up cause you can’t cut it in half so your answer is 23!!!!
