Understanding the Problem: The file size is determined by the number of bits used to represent each pixel and the total number of pixels in the image. We need to calculate the total number of pixels and then convert the total number of bits to kilobytes.
Calculations:
- Total number of pixels: Width x Height = 1024 pixels x 768 pixels = 786432 pixels
- Total number of bits required: Number of pixels x Bits per pixel = 786432 pixels x 3 bits/pixel = 2359296 bits
- Convert bits to bytes: 2359296 bits / 8 bits/byte = 294912 bytes
- Convert bytes to kilobytes: 294912 bytes / 1024 bytes/KB = 288 KB
Answer: The estimated file size of the bitmap image is 288 KB.
