Tall = Height. So the Height would be 10.72 inches.
Long = Length. So the rectangular prism would be 3.28 inches long.
I saw that depth can be the length from front to back is depth, but depth can also be the length from top to bottom. In this case, I think it is top to bottom. So the depth is 10.72 inches.
Tell me if this is incorrect. :)
Hoped this helped.
