To find the diagonal measurement of a 12 x 16 wood deck, you can use the Pythagorean theorem. The diagonal (d) can be calculated as ( d = \sqrt{(12^2 + 16^2)} ). This gives ( d = \sqrt{(144 + 256)} = \sqrt{400} = 20 ) feet. Therefore, the diagonal measurement of the deck is 20 feet.
using pythagorous 282 + 642 = 4880 square root = 69.856997 69.856997
This compares a linear measurement to a volumetric measurement. A foot is 12 inches and a cubic foot is 12 inches long x 12 inches wide x 12 inches high.
The diagonal is about 28.3 feet.
The diagonal of a 5 foot square is about 7.07 feet.
