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.
Know MoreCones 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.
Learn MoreTo calculate area, first determine the shape of the object. Next, apply the correct formula is needed, and substitute the values into the appropriate places. Finally, the equation should be solved to find the number that represents the area.
Full Answer >Cubic meters are calculated by finding the volume of an object. Wolfram MathWorld lists 15 volume formulae that aid in calculating an object's volume.
Full Answer >Cubic inches are the expression of the volume of a three-dimensional object. For typical square or rectangular areas, multiple the length of each side in inches, according to Math.com.
Full Answer >Cubic yards can be calculated by multiplying the length by the width by the height of a given volume. For such a calculation, all three measurements must already be in yards. When necessary, convert from feet to yards by dividing the number of feet by three.
