Question

Tyler asks for a fish tank for his birthday. The tank he wants is a rectangular prism 20.25 inches long. 10.5 inches wide, and 12.5 inches tall. How much wrapping paper will his father need to wrap this fish tank.

Answer 1

2(20.25 * 12.5)+2(10.5 * 3)+(20.25*10.5) 
=781.875

Answer 2

The answer is 981.375
I found this answer by multiplying (length times height )times 2, (length times width)times 2, and (width times height)times 2. and then you add the three areas together.
