Airships and bodies of revolution use the volumetric coefficient of drag, in which the reference area is the square of the cube root of the airship's volume. Sometimes different reference areas are given for the same object in which case a drag coefficient corresponding to each of these different areas must be given.
For example, some animal unit calculations used in Texas assume that daily forage dry matter consumption by a 90-pound nanny Spanish goat is 4.5 percent of body weight. Thus the nanny:cow ratio of daily dry matter consumption is estimated at 4.5:26, or about 0.16. This yields the estimate that such a nanny is equivalent to about 0.16 animal ...
Dimensional weight, also known as volumetric weight, is a pricing technique for commercial freight transport (including courier and postal services), which uses an estimated weight that is calculated from the length, width and height of a package. The shipping fee is based upon the dimensional weight or the actual weight, whichever is greater.
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
Its volume would be multiplied by the cube of 2 and become 8 m 3. The original cube (1 m sides) has a surface area to volume ratio of 6:1. The larger (2 m sides) cube has a surface area to volume ratio of (24/8) 3:1. As the dimensions increase, the volume will continue to grow faster than the surface area. Thus the square–cube law.
Using this notation for a three-layered cube is more consistent with multiple-layered cubes. [8] Rotating the whole cube: The letters x, y and z are used to signify cube rotations. x signifies rotating the cube in the R direction. y signifies the rotation of the cube in the U direction. z signifies the rotation of the cube on the F direction ...

In geometry, sphere packing in a cube is a three-dimensional sphere packing problem with the objective of packing spheres inside a cube. It is the three-dimensional equivalent of the circle packing in a square problem in two dimensions. The problem consists of determining the optimal packing of a given number of spheres inside the cube.
