A cushion filled with stuffing. In geometry, the paper bag problem or teabag problem is to calculate the maximum possible inflated volume of an initially flat sealed rectangular bag which has the same shape as a cushion or pillow, made out of two pieces of material which can bend but not stretch.
This template calculates the volume of a three-dimensional space. This is for cubic feet, cubic centimeters, etc., not for converting linear measures to things like gallons. It only accepts numeric input, not units, and does not perform conversions.
The hexagonal packing of circles on a 2-dimensional Euclidean plane. These problems are mathematically distinct from the ideas in the circle packing theorem.The related circle packing problem deals with packing circles, possibly of different sizes, on a surface, for instance the plane or a sphere.
SI derived unit cubic metre, from base unit metre Orders of magnitude for volume Conversion of units for volume; 1 E-36 m 3 = 1 pm 3: 1 E-27 m 3 = 1 nm 3: 1 E-18 m 3 = 1 µm 3
A wooden hopper for grain, on a millstone. Materials can be added either manually or automatically to the top of a hopper. For dust collection, it enters the hopper from a collection device. For example, baghouses are shaken or blown with compressed air to release caked-on dust from the bag. Precipitators use a rapping system to release the dirt.

As the local density of a packing in an infinite space can vary depending on the volume over which it is measured, the problem is usually to maximise the average or asymptotic density, measured over a large enough volume. For equal spheres in three dimensions, the densest packing uses approximately 74% of the volume.
