There are 10 digits, but for a three digit number the first number cannot be a 0. Thus: there is a choice of 9 digits for the first (and last digit which must be the same), with 10 choices of digit for the second (middle) digit, making 9 × 10 = 90 such palindromic numbers.

To be a 3 digit palindromic number, it must be of the form aba.I assume that a 3 digit number must be at least 100 (so that 020 for example does not count as a 3 digit number):a can be any of the nine digits 1-9;for each of these b can be any of the ten digits 0-9Thus there are 9 x 10 = 90 three digit palindromic numbers.
There are far more than 13 non-palindromic three-digit numbers. A palindrome is a word or number that is the same backwards as forwards; for example, 727. Thus, the FIRST thirteen non-palindromic three-digit numbers are 100, 102, 103, 104, 105, 106, 107, 108, 109, 110, 112, 113, and 114.

A single number cannot produce a product.
343 is the palindromic and cube number.7*7*7=3437 is being times three times by itself to get this palindromic and cube number.Also 1331 is a palindromic and cube number.11*11*11=133111 is being times three times by itself to get this palindromic and cube number.
