That's virtually unlimited as it's a human concept, check the back of a 1940's school notebook.
But just to get you started
foot, inch, cubit, meter, fathom, mile, nautical mile, light year, parsec, plank length,
have fun.
There is only one equilateral triangle with a perimeter of 60 units. Its side lengths are integers.
0.359 liters is 359 milliliters. Liters are units of volume, meters are units of lengths.
The area of a regular hexagon with side lengths of 10 units is about 259.8 units2
. . . has edge lengths of 5 units.
the units for area are always stated as a square of some units of lengths?
You can mutiply or divide the units to find the answer.
10(radical "2") units, or about 14.1 units.
There are many units which are used to measure the lengths of the object . The smallest unit of length is fero meter.
Lineal feet are units for measuring lengths.
Since the perimeter is a sum of lengths, it will also be a length.
There is no relationship between units of mass and either length of capacity. Units of capacity are the cubed units of length.
A cube has 12 edges. With a total length of 48 units, each edge is 48 units ÷ 12 = 4 units volume = edge_length3 = (4 units)3 = 64 cubic units.
