Answer 2

1 MB = 1024 KB

1 KB = 1024 Bytes

1 Bytes = 8Bits

Now, 500 MB = 500 x 1024 x 1024 x 8 = 4194304000 bits

Now, total pixels for a single photograph = 512x512 = 262144 pixels

Since, each picture have 262144 pixels, each pic will occupy 262144 bits of storage.

Total camera storage given is 4194304000 bits

Divide the total bits by bits occupied by a single photo, i.e $\frac{4194304000 bits} {262144 bits} = 16000$

Hence, 16000 such photo can be stored in a camera of capacity 500MB
