Total square feet: 169.0 (13 x 13 = 169)
19*13 = 247 square feet.
13 feet is 3.9624 metres, 17 feet is 5.1816 metres - multiply the two together and you get 20.5316 m2
To calculate the amount of gravel needed, first convert the dimensions to consistent units. The area is 13 feet by 9 feet, which equals 117 square feet. The depth of 4 inches is equivalent to 1/3 of a foot. Therefore, the volume of gravel required is 117 square feet × 1/3 foot = 39 cubic feet.
Assuming it is a rectangle, it is 156 feet2.
Total square feet: 169.0 (13 x 13 = 169)
Total square feet: 429.0
13 feet 10 inches is 4.22 meters.
3 linear measurements yeild VOLUME not AREA.
13 feet = 3 962.4 millimetres
13 feet x 3 feet = 39 square feet.
19*13 = 247 square feet.
13 times 20 = 260 square feet
15 feet * 13 feet = 4.572 metres * 3.962 metres = 18.116 sq metres.
That is 160 inches
13 feet is 3.9624 metres, 17 feet is 5.1816 metres - multiply the two together and you get 20.5316 m2
