an electronic manufacturer wants to ship a stereo system. The system includes the following components:
1 Receiver 20in. x 8in.
1 CD Player 20in. x 8in. x 5in.
1 Dual Tape Deck 20in. x 8in. x 6in.
2 Half-Cylinder Speakers, each with a height of 22 in. and a radius of 4 in.
To keep the components secure, all remaining space in the box must be filled with packing filler. What is the aproximate number of cubic inches of filler needed to pack one box?
