We are given a boxplot that contains some data. We will use the information below to analyze the given question.
STEP 1: Median
From the image above, we can see that the median represents the line drawn inside the box
This gives;

STEP 2: Interquartile range
The interquartile range is the difference between the third quartile and the first quartile.
So you need to find the volume of the rectangular prism and the equation for that is V=l×w×h. If you plug those numbers in you'd get 9×12×23=2,484. If you multiply 2,484 by

because you'd have to pour out

of the water out so that it's only

of the volume of water is left. 2,484×

= 828mm.
