A Cubic Foot Is 12 Inches Wide X 12 Inches High X 12 Inches Deep. 12 X 12 X 12.
1ft length x 1ft width = 1square ft
1 foot = 12 inches (1 foot) x (1 foot) = (1 x 1) (foot x foot) = 1 foot2 (12 inches) x (12 inches) = (12 x 12) (inches x inches) = 144 inches2
if you mean 11 foot diameter 11 x 12/2 = 66 inch radius V = pi x 662 x 30 = 410,335.2 (divide by 231) = 1776.34 gallons
18 x 18 inch square is equal to 3/2 x 3/2 foot square = 9/4 square foot. To cover 154 foot square (you don't mean 154 square feet) is (154 x 154) / (9/4) = (154 x 154 x 4) / 9 = 10540.44, so you will need 10541 tiles
A Cubic Foot Is 12 Inches Wide X 12 Inches High X 12 Inches Deep. 12 X 12 X 12.
1ft length x 1ft width = 1square ft
Do you mean the square root? The square root of 4 is 2. A square foot is a two dimensional unit of measurement for area. AKA: Length X Width. so... a square foot of 4 could be 1 x 4, 4 x 1, or 2 X 2
(7 feet) x (4 feet) x (1 foot) = 28 cubic foot
1 foot = 12 inches (1 foot) x (1 foot) = (1 x 1) (foot x foot) = 1 foot2 (12 inches) x (12 inches) = (12 x 12) (inches x inches) = 144 inches2

if you mean a 30 foot diameter circle, then pi x 152 x 3 = 2119.5 cubic feet of dirt
If you mean the diameter is 27 feet, then the radius is 13.5 A = pi x r2 = 3.14 x 13.52 = 572.265 sq ft
The volume of a rectangular object is equal to Length times Width times Height.
One square foot is 1 foot X1 foot, 1 foot square is also 1 foot x 1 foot. The only difference is that in 100 square feet it would be 10 x 10 or 5 x 20 etc but in a 100 foot square it is 100 feet X 1 foot only.
if you mean 11 foot diameter 11 x 12/2 = 66 inch radius V = pi x 662 x 30 = 410,335.2 (divide by 231) = 1776.34 gallons
18 x 18 inch square is equal to 3/2 x 3/2 foot square = 9/4 square foot. To cover 154 foot square (you don't mean 154 square feet) is (154 x 154) / (9/4) = (154 x 154 x 4) / 9 = 10540.44, so you will need 10541 tiles
