A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The volume of each small box is 8 cubic feet and the volume of each large box is 23 cubic feet. What would be the total volume, in cubic feet, of 11 small boxes and 13 large boxes? What would be the total volume, in cubic feet, of s
s small boxes and
l
l large boxes

The word EACH in math means multiply!

Therefore 11 X 8 = 88 cubic feet form the small boxes.
23 X 13 = 299 cubic feet for the large boxes
TOTAL = SMALL + LARGE
TOTAL = 88 + 299 = 387 cubic feet

Part 2: total = small + large
Each small is 8 cubic feet and the number of small boxes is “s” so each means multiply so 8s gives us the total volume from small boxes. Large boxes are 23 each so:
Total = 8s + 23l
