Question

Marley needs to store ten 8 bits colours images in a file for his project. Each image is 500 pixels wide and 300 pixels high. Calculate the total file size in megabytes for all markets images

Answer 1

• Answer:
• Calculate file size = 500 * 300
• Multiply by 10 for the ten images = 500 * 300 * 10 = 1,500,000
• Multiply the color depth i.e. 8 = 1,500,000 * 8 bits
• 4) then divide by 8 to convert to kilobytes = 1,500,000 * 8 / 8 = 1,500,000 bytes
• then divide by 1024 to convert to kilobytes = 1,500,000 / 1024 kB
• Then divide by 1024 again to convert to megabytes  = 1,500,000 / 1024 / 1024 MB = 1.43 MB
