## Main Question or Discussion Point

Hello

A manufacturer produces blocks of metal of

length 100 standard deviation 2,

width 200 standard deviation 1

depth 150 standard deviation 3

The mean volume will be 100x200x150 but what will its sd function be? (The figures I've given are just for clarity)

Thanks in advance, I've really no idea of how to tackle this problem.
