it isnt It is not stronger. True, a 3-leg will not wobble because 3 points define a plane. However, a 3-legged table will tip over more easily than a 4-legged table. I suspect some science guru has done the physics on this and can prove what I say.
Yes. This is because any three points will always be coplanar, but a fourth point may not be.
9 tables and 12 stools
Yes. 3x18=54.
Four four-legged turtles can not outrun faster four legged creatures like rabbits even if they could run four times faster.

Because the three feet of the tripod are on the same plane, even if one leg is shorter it will not waver or stumble. However, with four legs, if one leg is shorter it will end up in two planes, or two tripods, and will always waver from one plane to the other, thus making the chair/table unstable. Chairs and tables are probably four legged because they are rectangular. If you want a three legged table you would need to have an extra sphere/block that has three legs branching out, and it would be more expensive.
Either the legs are not secure to the frame, or the table is not level.
When you have a four legged stool it can be unbalanced if one of legs is a different length than the others. if you have a three legged stool than even if one of the legs is uneven it will still balance evenly.
A bedside table is a simple four legged table, while a nightstand is more akin to a cabinet or drawer chest.
A small seat that has three legs as opposed to four (or more)
On a four legged chair, if any of the legs are not as long (or longer) as the others, the chair will wobble. On a three legged stoll, if one of the legs are different, the chair will only be uneven or fall over (depending on how drastic the difference is).
Another name for a four legged animal is a quadruped.
There would have to be trillions of four-legged animals that exist on Earth.
Three points determine a plane. To put it another way, a plane can always contact any set of three points. So the tips of the legs of a 3-legged support always contact the floor. A 4-legged support has four possible sets of three legs, i.e. four possible planes that it can contact. Unless all four legs are exactly the same length, their ends don't all lie in the same plane. When set down on a single plane ... like the floor ... the support winds up wobbling among different sets of three points.
All four-legged animals are called Quadrupeds, 'quad' - four; 'ped' - foot.
