Final answer:

To find the total weight of the load, add up the weight of each item: couch, chair, piano, and boxes. The total weight is 710.13 pounds.

Explanation:

To find the total weight of the load, we need to add up the weight of each item. Given that the couch weighs 147 pounds, the chair weighs 67.7 pounds, the piano weighs 3.6x10² pounds, and the boxes weigh 135.43 pounds in total, we can simply add these values together.
