that's not geometry.
6*6*5=180 in^2
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.
An area 10 foot x 10 foot is 100 square feet. 100 cubic feet of sand would cover it with a one foot deep layer of sand. If the sand needs to be 6 inches deep, then 50 cubic feet are be needed, or 25 cubic feet if the sand is to be 3 inches thick.
Diameter = 26 feet so Radius = 13 feet Then volume = π*r2*h where h = 4 inches = 1/3 feet So V = 176.98 cu feet (to 2 dp)
The 4 inches is 4/12 of a foot or 1/3 foot. Length times width times height is the volume, so 2856 (the area in square feet) times 1/3 (the depth in feet) = 952 cubic feet.

2 inches = 1/6 foot Volume = 3,500/6 = 5831/3 cubic feet = 21.605 cubic yards
That hole is 6 feet deep or 72 inches deep.
85.5 inches. 12 inches in a foot. 85.5/12=7.125 feet= 7 feet 1 1/2 inches
To calculate the volume in cubic feet, you would multiply the height, width, and depth together and then divide by 1728 (since 1 cubic foot is 1728 cubic inches). So for the dimensions given, the volume would be (67 * 33 * 34) / 1728 = 118.23 cubic feet.
To convert inches to feet just divide by 12 (since there are 12 inches per foot) -42 / 12 = 3 feet 6 inches

Diameter = 26 feet so Radius = 13 feet Then volume = π*r2*h where h = 4 inches = 1/3 feet So V = 176.98 cu feet (to 2 dp)
The 4 inches is 4/12 of a foot or 1/3 foot. Length times width times height is the volume, so 2856 (the area in square feet) times 1/3 (the depth in feet) = 952 cubic feet.
Without depth, the circle is a flat figure without volume ... zero cubic units.
