I recommend writing down each area and perimeter formula on a note sheet so you can look them up quickly

good, now multiply that by 4 afterwards, add that to 2.89

jim_thompson5910Best ResponseYou've already chosen the best response.1
you got 16.32 for the lateral surface area 2.89 was the base area

so total surface area = base area + lateral surface area total surface area = 2.89 + 16.32 just summing things up (you probably already know by now)
