Question

Suppose a digital camera has a storage capacity of 256mb. how many photographs could be stored in the camera if each consisted of 1024 pixels per row and 1024 pixels per column if each pixel required three bytes of storage?

Answer 1

1024 * 3 + 1024 * 3 = 6144
6144 bytes = 0.006144 megabytes
256 mb / 0.006144 mb = 41666.67(rounded)
You can take 41666 photos.

Hope this helps!
