HELP!!! Math

You visit the Grand Canyon and drop a penny off the edge of a cliff. The distance the penny will fall is 16 feet the first second, 48 feet the next second, 80 feet the third second, and so on in an arithmetic sequence. What is the total distance the object fall in 6 seconds?

distance = 16t^2
when t = 6
distance = 16(6^2) = 576 ft
btw, It might be a federal offense to drop a coin into the Grand Canyon.
