3.a. 2²⁰ X 600 x 8 = 5,033,164,800 bytes or 5 Mbits

b. 8 x 54 x 60 x 1000 = 25,920,000 bytes or 25.9 Mbits

100 x 1024 x 768 x 8 = 629,145,600 bytes or 629.1 Mbits

30 x 60 16000 x 6 = 172,800,000 bytes or 172.8 Mbits

Total 827.8 Mbits

5000/827.8 = 6 volumes per CD

c. 827.8 Mbits/1.544 Mbps = 535.9 sec / 60 min per sec = 8.9 minutes or about 9 minutes

d. 25.9/3 = 8.6 Mb

629.1/10 = 62.9 Mb

172.8/2 = 86.4 Mb

Total 157.9 Mb

5000/157.8 = 31.6 or about 32 volumes per CD

157.8/ 1.544Mbps = 102 sec = 1min, 42 sec
