Math Is Fun Forum

After 9 come the letters.

Base 10 is the system we use for arithmetic. Also, base 16 and hexadecimal (hex) are the same thing.

You can not simply derive measurements such as height, width, and depth for a complicated shape such as a human body or car with more data. Even if you had this data, its extremely difficult to do. If your object was simple such as a cube, cylinder, or triangle and had more data,... we could calculate this a lot easier.

Not knowing any more than just the SA of say a box,... we can derive dimensions for say a box but there are infinitely many dimensions. This means the box can be of any shape or even size. If you give us the SA, L, and W, we can calculate the depth for example. If you only give the SA and L, that would mean the width and depth would be infinite.

Those would be tricky to work out.  There's no easy formula as people and cars have many shapes.

You could estimate by making a square grid and holding it against the surface and counting up squares.  Hard to be accurate though.

There are formulas for some solids: sphere, cone, pyramid etc.
