200 shells per carton. 600 cigarettes per pound so 16 ounces divided into that is .03 ounces per cigarette or 6 ounces per carton. so 0.6 ounces per pack so the shell weighing .4 to .5 ounces makes sense I guess.
A bit map (often spelled bitmap) defines a display space and the color for each pixel or bit in the display space. A Graphics Interchange Format and a JPEG are examples of graphic image file types that contain bit maps. A bit map does not need to contain a bit of color-coded information for each pixel on every row. It only needs to contain information indicating a new color as the display scans along a row.
The most straightforward way of storing a bitmap is simply to list the bitmap information, byte after byte, row by row. Files stored by this method are often called RAW files. The amount of disk storage required for any bitmap is easy to calculate given the bitmap dimensions (N x M) and colour depth in bits (B).
