To draw customers in, Putnam's Puzzles just installed a rotating neon sign outside its shop. The sign is shaped like a cube that is 2 1/2
feet along each edge.
What is the volume of the sign?
Write your answer as a whole number, proper fraction, or mixed number.
The volume of a cube is calculated by multiplying the length of one side by itself three times.
Volume = (2.5 feet)^3
Volume = 15.625 cubic feet
Therefore, the volume of the neon sign cube is 15 5/8 cubic feet.
