A cubic yard is 3 feet wide, 3 feet high and 3 feet deep, therefore 3 X 3 X 3 = 27 cubic feet in a cubic yard.
It works out as 33.817 cubic feet rounded to three decimal places
28,152 cubic feet
Not possible to convert between a length unit and a volume unit.
A range this size will take up 15.2 cubic feet.
You need to tell us how deep it is.
The volume is 36*68*31 = 75,888 cubic inches = 75,888 / (12*12*12) = 43.91667 cubic feet.
= (65/12) x (35/12) x (350/12) cubic feet
Volume = Length*Depth*Height = 2*4*1.5 = 12 cubic feet
You MUST state what units are the measurements in - millimetres, inches, feet, or what.
Imagine a box 3 feet high by 3 wide and 3 feet deep. That is one (cubic) yard.
