The roof of a building is shaped like a square pyramid, with a base of 18m by 18m. If the slant height of the roof is 12m and roofing costs 5.75m2, how much will it cost for roofing material?

This is the last question for my homework could u answer this for me to find how much the cost is?

Thanks.
