Hello everyone! I am new to the forum and it looks an excellent forum, and busy too, which is always good! I feel a bit of a novice for asking this, but i have never been that great at Maths or Physics, so bear with me please. 1. The problem statement, all variables and given/known data Basically, i would like to know please, if i was dealing with a density which has a minus at the end of the cubic metres, how do i go about that? I need to work out the density of an object with the calculation... 5 x 103 kg m-3 2. Relevant equations 3. The attempt at a solution Im guessing that when there is 5 x 103 that means 5 x 30,000? But it is just the m-3 which then confuses me. Many thanks and again sorry for the novice post.
