Suppose you are trying to find the volume of a box based on the given measurements for the length, width, and height of
the box, where the height was measured in two parts.
length, I = 2.20 in
width, w = 3.11 in
height, h = 10.4 in + 1 in
Calculate the height, h, of the box, first keeping all digits, then rounding to the proper number of significant figures.
unrounded h =
in
rounded h =
