How to make your Goat Float
Weight of water: a gallon of water weighs approximately 8.33 pounds
One gallon liquid US in volume(amount of space) converted to cubic inches equals precisely to 231.00 cu in – in3
Phil’s goat weighs 200lbs.
- How much water will we need to displace?
We know a gallon of water weighs 8.33lbs
What is the Goat’s weight in gallons?
200lbs/ 8.33lbs = 24.09 gal
How much volume (in space Cu/in) does 24.09 gal displace?
We know that 1 Gal. equals precisely 231.00 cu/in – in3 (that is how much space it takes up!)
If we multiply the #of gallons (we got for the goats weight) by the volume of one gallon we find the volume of water the will be displaced.
24.09 gal x 231 cu/in = 5566.26 inches
Answer: In order for the goat to float we must displace 5566.26 cubic inches of water.
- We need to figure out how big our boat will be so it is stable (not too tippy) and strong enough(structrure) to support our weight with out collapsing the boat.
I know my paper for the boat is 38” (inches) wide. I will make the walls of the boat 6” tall (because that seems to be about right based on how much a canoe and kayak sink in the water).
If I subtract 12” (total of two 6” walls) from 38” I get 26” for the bottom of the boat.
This is the one number I know in the Volume formula (LxWxH=Volume). To get started I take my total volume from above 5566 cu/in. and set my height at 1.
L x 26 (wide) x 1 (high)=5566 cu/in
Answer: The length is 214 inches (5566/26=214) but keep reading…..
That will make a really long boat and I want a boat closer to 100 inches. So ajust the Height until the Length is closer to 100.
