The cubic feet formula depends on the shape of the object for which one is calculating volume, but for a cube, v=a^3, where a is the length of one side in feet. For cylinders and prisms, the formula is the area of the base multiplied by the height.
Continue ReadingCones and pyramids also use the same formulas for determining their volumes. For both of these shapes, v=(1/3) b*h. Calculate the area of the base of a cone as a circle with a=pi*(r^2) and the base of a pyramid using the appropriate area formula for the shape.
Use caution when converting from cubic feet to cubic inches or cubic yards. One cubic foot equals 12 x 12 x 12 cubic inches, or 1728 cubic inches. A cubic foot is 1/27 of a cubic yard.

Full Answer >The volume of a rectangular-shaped object can be determined using an instrument called the "Vernier caliper." The product of length, breadth and height of a rectangular-shaped object gives its volume. For determining the length, breadth and height of the object with maximum accuracy, a Vernier caliper is used.
Full Answer >In math, volume is the amount of space inside a three-dimensional object, or its capacity. A measurement of volume offers insight into how much liquid or how many physical objects a person can fit into an object. Knowing the volume of a truck is helpful when planning a move.
Full Answer >Density is the mass of an object divided by the volume of space the object takes up. This expression gives the numerical amount of mass per unit volume of the object's material.
