Depending on shape (Gun,Performance longboard etc.) 20 1/2 - 24"
find the width of a rectangle if its area is 9/28 of a square foot
Depends on height and weight, otherwise a longer wider board is best. Sometimes a soft top board helps. If your taller and heavier a 9 foot/ 10 foot might be the answer shorter smaller kids 7'6/8 foot would be good.
8 or 9 foot, either one is common.
Multiply width by length to get the area. The answer would be 54 square feet or 6 square yards.
For a 9 foot table you should get a 10 foot table runner. This will allow a portion of the runner to hang off each side, as it should.
multiplythe width by length ie 18feet x 12feet =216 divide by 9 =24sq yards
You should be 169 to 202 lbs.
(9 foot) * (3 inches) * (1.5 inches) ≈ 7.9641131 liters (9 foot) * (3 inches) * (1.5 inches) ≈ 7,964.1131 cubic centimeters ≈ 7,964.1131 mL (9 foot) * (3 inches) * (1.5 inches) = 486 cubic inches = 486 in3 (9 foot) * (3 inches) * (1.5 inches) = 0.28125 cubic feet = 0.28125 ft3
90 square feet. This is an easy calculation - just multiply the length by the width(9*10) The answer is the number of square feet.
156
The crease should have about a 9 foot radius
Tread width is the distance from front to back on a stair tread, parallel to the length of your foot which you place on the tread, unless you walk duck style. Typical tread widths range between 9-12".
