Question 872078: Hello I have a question about surface area. The problem has a picture of a hexagonal pyramid with a slant height of 12cm and a side length of 4cm. The question says to find the surface area. I have used the formula, Google, and my parents but no one gets any of the answer options. It is A.144cm B.144+24 radical 3cm C.196cm and D.288cm. I would love some additional help!
