The volume of a cylinder with a radius of 2 inches by 4 feet high is: 0.349 cubic feet.
Volume = 3,015.92895 ft3
Volume of greenhouse: 40*15*10 = 6000 cubic feet
With difficulty unless other dimensions are given.
Volume = Length*Depth*Height = 2*4*1.5 = 12 cubic feet
The volume of a cylinder 2.45 across by 1.50 high is: 7.072 cubic units.
The volume of a cylinder 2 feet in diameter and 5 feet high is: 15.7 cubic feet.
The volume of a cylinder 8 feet high and 3 feet wide is: 56.5 cubic feet.
The volume of a cone 4 feet high with a base diameter of 13 feet is: 177 cubic feet.
The question cannot be answered because the dimensions of the measures are not given. It should be obvious to anybody that the volume of a container which is 14.25 feet high and 8.5 feet across will not be the same as one which is 14.25 inches high and 8.5 inched across!
The volume of a cylinder with a radius of 2 inches by 4 feet high is: 0.349 cubic feet.
