You are planning to install sod in your yard. You calculated that the installation will require 240 rolls and you have placed an order. Unfortunately, the delivery person read the address incorrectly and dropped off the sod at a house a block away. The delivery truck came from out of town and will not be able to return to help you move the sod. You begin to contemplate the effort it would take to move the sod, and you consider various means of transportation. Each piece weighs about 12 kg, so you make the following estimates.
Transportation Method |
Number of Rolls Moved at a Time |
Neighbour’s Cat | 0.2 |
7-year-old Next Door | 0.5 |
12-year-old Next Door | 1 |
Yourself | 2 |
You and a Friend | 4 |
Wheelbarrow | 5 |
Wagon | 8 |
Car Trunk (This will be messy.) | 15 |
Pick-up Truck | 40 |
