If the shape is a cube then the length, width and height will be the same and the dimensions will be the cube root of 19.7 = 19.71/3 = 2.7 ft.
(2.7 ft x 2.7 ft x 2.7 ft = 19.7 cu.ft.)
There are an infinite number of combinations of length x width x height that will give 19.7 cu.ft.
To convert length, width, and depth into cubic feet, multiply the three dimensions together. For example, to convert dimensions in feet, the formula would be: Length (ft) x Width (ft) x Depth (ft) = Cubic Feet. This will give you the total volume of the object in cubic feet.
The volume of dirt to be hauled away is 85,000 cubic yards. Calculate the volume by converting the dimensions to yards (700 ft = 233.33 yd, 200 ft = 66.67 yd) then multiply the dimensions together (233.33 yd x 66.67 yd x 85 ft).
To convert yards to feet, multiply by 3. So, the dimensions of the cuboid in feet are 9 ft x 21 ft x 27 ft. To find the volume, multiply these dimensions (9 x 21 x 27) to get 5103 cubic feet.
To calculate the cubic feet of dirt, measure the length, width, and depth of the area in feet. Then, multiply the three dimensions together to get the volume in cubic feet. Formula: Length (ft) x Width (ft) x Depth (ft) = Cubic Feet of Dirt.
The question, as stated, cannot be answered sensibly. A cubic foot is a measure of volume, with dimensions [L3]. A yard is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
