Hello Everyone, I'm new to the forum. A friend of mine told me how helpful you guys were, and I was wondering if anybody here would answer my question regarding scientific notation.
I've recently been required to revise scientific notation, which is a subject I havn't studied for many years, and that combined with my mathematical ineptness has led to my confusion.
I understand it loosely, but came across a question, the answer to which, has thrown me.
I was asked to calculate the volume of a box, having been given it's length, width and height.
Width = 2.56 x 10 to the power of -6m
Length = 1.4 x 10 to the power of -7m
Height = 2.75 x 10 to the power of -4m
I simply multiplied the digits together to get 9.856 and then multiplied the powers.
I ended up with the answer 9.856x10 to the power of -17 m3
I think that's the correct answer, but doesn't that mean the volume is smaller than each of the length,width and height? Since there's more 0s after the decimal point. How can a volume be smaller? I'm sure I've missed something obvious but I just need a prod in the right direction!
Thanks in advance to anyone who helps!
