The formula of a volume of a rectangular prism: V = lwh
l - length
w - width
h - height
We have the volume:
3.7491739193721... because rational numbers are numbers like -3 -2 -1 0 1 2 3 and decimals like 3.3333333 and 1.62162162162162 because they repeat the same numbers like a pattern, with 3 repeating or 162.The decimal 3.7491739193721... is not rational, or irrational because it is not repeating or terminating, or stopped.
The sum of these will simply be the sum of all the numbers 1 through 26, which is 351.
