Hint
The answer involves multiplication (for example, 9 x 8 = 72).
Answer
468.
Reasoning
If we split each line in the following way:
98 68 88
72 48 64
14 32 24
Each new line is generated by multiplying the digits two at a time and writing the result below.
For example, 9 x 8 = 72, so 72 appears directly below 98.
And 7 x 2 = 14, so 14 appears directly below 72.
Double-Checking
9 x 8 = 72 and 7 x 2 = 14.
6 x 8 = 48 and 4 x 8 = 32.
8 x 8 = 64 and 6 x 4 = 24.

Hint
Start by looking at the consonants and vowels (AEIOU).
Answer
65 tonnes.
Vowels (AEIOU) are worth 3 and consonants are worth 5, added together and then multiplied by the number of ingots.
So TIN has 1 vowel (worth 3) and 2 consonants (worth 10).
Added gives 13, then multiplied by 5 ingots = 65.
