| + | === What is the volume of the tub? === | ||
| + | |||
| + | Volume = area * height = pi*r^2 * h = 3.14*3' | ||
| + | |||
| + | === How many gallons is that? === | ||
| + | |||
| + | Approximately 846 gallons, per google | ||
| + | |||
| + | === what is area of bottom? === | ||
| + | |||
| + | area = pi*r^2 = 3.14 * 3 * 3 = 28 square feet | ||
| + | |||
| + | === Approx how many linear ft of boards will that take? === | ||
| + | |||
| + | Our boards are appox 11" wide, let's assume 12" for easy math, this is an approximation. Also, we need to be slightly smaller than 6' wide anyway. | ||
| + | |||
| + | So we need about 28 lf of boards. It will be more than that, we're going to lose some to tongue and groove. | ||
| + | |||
| + | === Approx how many staves will we need? === | ||
| + | |||
| + | circumference = 2*pi*r = 2*3.14*36in = 226in | ||
| + | |||
| + | assuming 5" staves, we'll need 226in/5in = 45 staves | ||
