Exercise 2: Order the Image Calculation Steps
Arrange the steps in the correct order to calculate image file size.
Task: Calculate file size of a 1024 × 768 image with 24-bit colour, answer in MB.
Multiply total pixels by colour depth (24 bits)
Divide by 1,000,000 to get MB
Divide by 8 to convert bits to bytes
Calculate total pixels (1024 × 768)

Exercise 3: Order the Audio Calculation Steps
Arrange the steps in the correct order to calculate audio file size.
Task: Calculate file size of 3-minute stereo audio at 44,100 Hz, 16-bit, answer in MB.
Multiply by bit depth (16)
Divide by 8 to get bytes
Convert duration to seconds (3 × 60 = 180)
Multiply by 2 for stereo
Multiply sample rate by duration (44,100 × 180)
Divide by 1,000,000 for MB
