I have to assume that the 24, the 72, and the 18 are feet.
If those are the dimensions of a rectangular prism, like a box, a crate,
or a humongous block of ice, then
Volume = (length) x (width) x (height) =
(24-ft) x (72-ft) x (18-ft) = <em>31,104 cubic ft</em>
If those numbers are <u>inches</u>, then here's the easy way to handle it:
24 inches = 2 ft
72 inches = 6 ft
18 inches = 1.5 ft
Volume = (length) x (width) x (height) =
(2ft) x (6ft) x (1.5ft) = <em>18 cubic feet
</em>
Solution:
Let the speed of cyclist without any wind = x miles per hour
Speed of cyclist when speed of wind increases by 2 miles per hour = (x + 2 )miles per hour
Also , relation that is given between speed of cyclist without wind and with wind is :Riding with the wind at her back, a cyclist takes an hour less time to cover 80 miles than without any wind.
Converting this statement into terms of equation:
→→→To solve the Quadratic equation of type : a x² + b x + c=0, I have used discriminant method, to find the roots, which is x=
Speed of cyclist without wind = 11.68 miles per hour
Speed of cyclist when wind is flowing = 11.68 +2 = 13.68 miles per hour

Answer:
Quinn did not make a mistake. This is because everything she did is correct and also if we calculate the expression without doing anything she did, we see that she has the right answer.
