Q is inversely proportional to the cube of T

When T=5, Q=12.6

It's as if someone added a decimal point and then added a 0.1 although it is never so with maths....thankfully.

Proportionality afaik requires a variable equal to another variable multiplied (or divided) by a constant.

; is proportional to . An inverse proportionality would be

They did mention it was inversely proportional, right? That means;
