The volume of a rectangular prism can be found by multiplying its length, width, and height. In this case, the box that the kite came in has dimensions of 20 1/2 inches by 9 1/2 inches by 2 inches.
To find the volume of the box, we can convert the dimensions to decimals and multiply them:
Volume = length x width x height
Volume = 20.5 inches x 9.5 inches x 2 inches
Volume = 388.75 cubic inches
Therefore, the volume of the box that the kite came in is 388.75 cubic inches.
