Final answer:
The total cubic inches of packing peanuts in the shipment is 3645 cubic inches.
Step-by-step explanation:
To calculate the cubic inches of packing peanuts in the shipment, we need to find the volume of each cube and then multiply it by the number of boxes. The volume of a cube can be calculated by multiplying the length, width, and height. In this case, each dimension of the cube measures 9 inches. So the volume of one cube is 9 x 9 x 9 = 729 cubic inches. Since there are 5 boxes in the shipment, we multiply the volume of one cube by 5 to get the total cubic inches of packing peanuts in the shipment. 729 x 5 = 3645 cubic inches.
