RE: What is the height of the table?

This stimulated my brain... the table is 150 cm.

Cat = A
Table = B
Turtle = C

Adding and subtracting all the parts, plus two (2x) tables, equal to the two distances added together =

(A + C - A - C) + 2B = 170 + 130
2B = 300
B = 150

The table is 150 cm Cannot determine the height of the cat and turtle, except that the cat is 20 cm taller:

170 - 150 = 20
-130 + 150 = 20

If I were to estimate based on the picture, I'd say:

Table = 150 cm
Cat = 60 cm
Turtle = 40 cm
