Question

An image which is 6 inch x 4 inch has a Resolution of 300ppi

i) If it is a gray scale image, calculate the size of the image in bytes.​

Answer 1

Explanation:

Since the resolution is 300 dpi, it means that each inch is 300 pixels across. As the image is 8 inches wide that means there are 2,400 pixels in width (8 x 300). Likewise, as the image is 12 inches long, the image is 3,600 pixels in length (12 x 300).
