The middle dimension is missing from the question. If that is x then the volume is 12*x cubic feet.
If the whole container is rectangular, then its volume is 18" x 24" x 30" = 12,960 cubic inches = 7.5 cubic feet = 56.104 gallons
12 cubic ft.
You mean volume in cubic feet. The volume of a rectangular prisim is the area of the base in square feet times the altitude or height in feet. The area of the base is the length of one side in feet times the length of an adjacent side in feet.
192 cubic feet, or 7.011 cubic yards.
The container is 10 feet long, 4 feet wide, and 1 yard high, which is equivalent to 3 feet. To calculate the volume, multiply the length, width, and height. So, the volume of the rectangular container is 10 feet x 4 feet x 3 feet = 120 cubic feet.
The middle dimension is missing from the question. If that is x then the volume is 12*x cubic feet.
If the whole container is rectangular, then its volume is 18" x 24" x 30" = 12,960 cubic inches = 7.5 cubic feet = 56.104 gallons
Any container of any shape with a volume of 6.6841 cubic feet or more will do the job. For a rectangular container, multiply the (length) x (width) x (height). If the result is 6.6841 or more in feet, (11,550 or more in inches), you're in business.
Volume is 30 cubic feet.
12 cubic ft.
It is: 8*3*5 = 120 cubic feet
Its volume would be 343 cubic feet.
There is no direct conversion between gallons and feet as they are measuring different quantities (volume vs. length). If you specify the shape or container for which you need the conversion (e.g., a rectangular tank), a calculation can be made to determine the height in feet for a volume of 150 gallons.
Assuming the container is full at 1500 liters, the container's volume in cubic feet will be about 53 cubic feet (52.9720005, more precisely).
You mean volume in cubic feet. The volume of a rectangular prisim is the area of the base in square feet times the altitude or height in feet. The area of the base is the length of one side in feet times the length of an adjacent side in feet.
More information is required. Is the container a cube? Or a rectangular block, for example, 20 x 10 x 5? Is it a sphere? In this case, is 20 feet the radius or the diameter? Is is a cylinder? In this case, you need radius and height.
