Answer: 14,400 ft² = 0.330578 acres.
8 X 10 X x = 640ft3 80x = 640 80x/80 = 640/80 x = 8 The answer is 8 feet deep
80 feet = 0.024384 kilometers.
80*80 = 6400 square feet
200' long by 85'wide. All NHL rinks are the same by rule. Olympic ice hockey rinks are 30 meters wide by 60 meters long (98.4 feet by 196.8 feet).
39,600 cubic feet. 1,466 cubic yards or about 122 truckloads if it were non-compacted fill.
It is a measurement of area equal to 80 feet wide and 80 feet long.
Square feet is two-dimensional. A flat area 20 feet wide by 10 feet deep is 200 square feet. But cubic feet is three-dimensional. Think of a box 12" wide by 12" deep by 12" high. That's a cubic foot. To determine cubic feet, take the width x depth x height (in inches) and divide by 1728.
80' x 30' = 2,400 square feet.
800 feet
the docks is probably 80 to 100 feet and the solent 30-60 feet deep
80 feet
