The paint will fill the tray exactly. D. The paint will overfill the tray by 10.53 in3

I have detailed how to proceed to solve this question, why did you close that one and reposted it here? We don't seek answers here, we seek the path to the answers and understanding of these problems.

What you need to do here is to obtain the volume of the tray, and see if the paint could fill it Let's take for example the tray's volume is about 5 gallons and you have 10 gallons of paint, well, we can see that it will over fill by 5 gallons by doing PaintVolume - TrayVolume = 10 - 5 = 5 gallons overfill if we have on the other hand 3 gallons of paint, well, the tray will not fill completely 3-5 = -2, by 2 gallons

first change the cm to inches to work with one unit of measure and it is better to work with inches since we already have the volume in inches. given 1 inch = 2.54 cm how many inches are the equivalent of 4 cm? the tray is like a box the volume = length * width* depth you have the measurements plug the numbers and find the volume of the tray now, Billy has 1 gallon of paint. you are given that 1 gallon = 231 in3 so you know the volume of one gallon of paint and you calculated the volume the tray can hold compare these amounts using the scenarios and decide which one is true. when considering option A remember to use the same unit. cm with cm or in with in
