**How to make your Goat Float**

The Facts:

**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.

Goat Floats!
