If i have a number of bp in chromosome 1 for example(298,295,559 bp) can I use this number to find the number of bp in chromosome 3.
You cannot. BP numbers vary between the chromosomes. Chromosomes are numbered by size, so you can always say that 2 is smaller than 1; however, there is no function to determine the exact size of one chromosome based on the exact size of another.
Chromosomes vary in length and there is no reason to expect a nice relationship in the relative length of chromosomes.
However, by definition chromosomes are numbered from the longest to the shortest (except for the concern of sexual chromosomes). The chromosome 1 is the longest, the chromosome 2 the second longest and the chromosome 8 is the 8th longest. Following @ping comment
Also note that human chromosomes 21 and 22 are numbered the "wrong" way round in that 21 is actually smaller than 22; so even for autosomes using the numbering to determine size rankings doesn't necessarily work.
In consequence, if you know that the chromosome 1 is x bp (base pairs) long, then the only thing you can tell about chromosome 3 is that is has less than x base pairs. Note that x ≈ 250,000,000 base pairs in human.
