Question

Jamelia wants to store an image file. The image has an 8- bit resolution and is 150 pixels by 100 pixels in size. Calculate the file size of the image. Give your answer in kilobytes(kB).

Answer 1

To calculate the file size of the image, you can use the formula:

File Size (in kilobytes) = (Image Width x Image Height x Bit Depth) / 8 / 1024

In this case, the image has an 8-bit resolution, and its size is 150 pixels by 100 pixels.

File Size = (150 x 100 x 8) / 8 / 1024

File Size = (120000) / 8 / 1024

File Size ≈ 14.6484 kilobytes (rounded to four decimal places)

So, the file size of the image is approximately 14.6484 kilobytes.
