Jack is storing a rectangular box inside a cylindrical container. The container has a volume of \(980\pi\) cubic inches and a height of 20 inches. Which of the following dimensions could the box have in order to fit inside the cylinder?
Indicate all such values.
A. 3 inches by 6 inches by 12 inches
B. 6 inches by 9 inches by 15 inches
C. 10 inches by 10 inches by 10 inches
D. 8 inches by 9 inches by 16 inches
E. 11 inches by 15 inches by 18 inches
F. 9 inches by 9 inches by 20 inches
After some pondering, this is what I got!
Let's say that the diagonal of the rectangular box is equal to the diagonal of the cylinder, which is \(14\)
taking least of the two values from each option and trying to see if it fits
Option A -> \(3^2 + 6^2 <= 14^2\)
Option B -> \(6^2 + 9^2 <=14^2 \)
Option C -> \(10^2 + 10^2 > 14^2\) --> It is greater. Cannot be fit into the cylinder
Option D -> \(8^2 + 9^2 <= 14^2\)
Option E -> \(11^2 + 15^2 > 14^2\) --> It is greater.Cannot be fit into the cylinder
Option F -> \(9^2 + 9^2 <= 14^2\)
