An area is an area, not a volume. 20 by 26 = 520 square feet
4.6666666666666666666648 cubic feet
Cubic footage (or volume) is simply the length x width x thickness. 4 inches x 1ft/12 inches = 0.333 ft Therefore, the driveways volume is: 30ft x 15ft x 0.333ft = 149.85 cubic feet, or better to just say 150 cubic feet.
To Determine The Square Footage (A Unit of AREA) You Do The Following: Length x Width (in Feet) = Square Footage (written in Feet Squared or Feet^2) I think what you are asking is NOT for SQUARE FOOTAGE but for VOLUME measured in CUBIC FEET (Feet^3) VOLUME, in this case (since the measurements are RECTANGULAR) Are Determined By: Length x Width x Height (in Feet) = Feet CUBED (Feet^3 or Cubic Feet) 24 Feet x 18 Feet x 9 Feet = 3,888 Feet^3 or 3,888 Feet Cubed or 3,888 Cubic Feet Cubic Feet, Which I believe is what you are looking for, since you gave 3 measurements of Length, Width and Height; is the VOLUME with Length, Width & Height that You Gave.
using those dimensions, 38.89 cubic feet not square feet
This area has a volume of 208.33 cubic feet.
Assuming you mean a cubic construct that is 24 feet long by 1 feet wide by 2 feet deep, the answer is 48 cubic feet (24x1x2).
Area is length times width. The floor is 100 square feet.
6' x 36" (3') =18 Square feet L x W = Area this equation does not supply enough paramaters for cubic feet L x W x H = Cubic Area
The area of a rectangle that's 22-ft long and 6-ft wide is 132 square feet.
188 square feet. Multiply the length by the width. The result is the area in square feet.
4.5 x 9 x 1.5 = 60.75 cubic feet
You have to multiply the two dimensions to get the area. In this case the answer will be 117 square feet.
