Suppose you are trying to find the volume of a box based on the following measurements for the length, width, and height of the box, where the height was measured in two parts.

length, l = 2.2 in

width, w = 3.5 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.

Calculate the volume (V) of the box using V = l × w × h. Round to the proper number of significant figures.
