so, let's say the length is "L".
width = 2 shorter than L = L - 2.
height = 9 more than twice L = 2L + 9.
check the picture below.
keeping in mind that the volume of a <u>rectangular prism</u> is simply the product of its length, width and height, and since we know the volume has to be 45.
from those 3 factors, we get those solutions/zeros.
we can't use -5/2, or -3, because the length can't be a negative value, so L = 3.
that means the width = 3 + 2, and the height = 2(3) +9.
