The HPS has issued its standard, Surface and Volume Radioactivity Standards for Unconditional Clearance.
FORBES: Does The DoD Want To Kill Us All With Radioactive Nuclear Scrap Metal? No, No Not Really
Microplastics have larger surface to volume ratios, potentially facilitating contaminant exchange and have been shown to be ingested by a range of organisms.

But as an object gets smaller, the ratio between its surface area and its volume rises.
One could only conclude that analysts at government-sanctioned rating agencies were probably just skimming the surface, given the volume of securities needing to be rated.
Self-seeding may explain why large tumors tend to grow (in percentage terms) more slowly than small tumors: It could be that growth is a function of surface area rather than volume.
The result, they claim in a paper that will appear this month in the Journal of Physical Chemistry, is a nanofibre material with an extremely high ratio of surface-area to volume.
According to a recent report from Digitimes, Microsoft was only planning on having an initial shipment volume of one million Surface Pro units.

This is obviously less than what Microsoft planning with the Surface RT, which had an initial shipment volume of four million units.

Data from the Sharad (SHAllow RADar) instrument (on Mars Reconnaissance Orbiter), document that some of these glacial-like features, which you find at Mars' mid-latitudes, have a significant volume of ice left below a surface of rock debris.
This, in turn, means clever engineering can increase the surface area (and thus the storage capacity) without increasing the volume.
Airships demonstrate a law of increasing returns: doubling the length increases the surface area (and hence weight) by a factor of four while the volume (and hence lifting capacity) goes up by a factor of eight.
After all, 10% of its volume is typically above water and the other 90% is below the surface.
FORBES: Why 787 Dreamliner Battery Woes Are the Tip of Boeing's Iceberg
Satellites have long been used to track ice extent (area), but calculating the thickness of the marine floes requires the overflying spacecraft to gauge the difference between the top of the ice surface and the top of the water - a relatively simple calculation then gives the overall volume.
United Utilities said it was hampered by "the sheer volume of water and by the amount of damage that was caused to the road surface".
