According to the table, the given stack of numerals correspond to
15
7
19
13
11
0
(A shortcut for reading these numbers: each bar represents 5 and each dot represents 1. The disk just means 0. So for instance, 13 = 5 + 5 + 3 = 2 bars + 3 dots.)
Mayan numerals are expressed in base 20, so the number above is equivalent to
15×20⁵ + 7×20⁴ + 19×20³ + 13×20² + 11×20¹ + 0×20⁰
= 49,277,420
