You are participating in a fresh water fishing tournament with the goal of catching the heaviest fish. You are in the middle of the river when you finally get your catch; unfortunately, you realize that you left the spring scales in your car. All you have in the boat are the paddles, your 16 Oz coffee mug, some rope, measuring tape, and a plastic bag. Estimate the mass of the fish (in kilograms) using these items.
