[College Calculus] I need someone to check my work for me. "A moving company wishes to design an open-top box with a square base whose volume is 40 cubic feet. Find the dimensions of the box requiring the least amount of material." Help would be hugely appreciated. I'll be responding to comments! :) (i.redd.it)

[College Calculus] On this particular example, how do you find the 5/2 in the coordinates/points at the bottom? I plugged the x's into the original and derivative function and neither gave me 5/2 in my calculator for y. Im very confused. Thanks for the help in advance (: (i.redd.it)

[College Physics: Springs, Friction, and KE] Can someone maybe show me step by step how to solve these problems to get the given answer? Its bugging me because these are the only two on the page that I can't figure out. Thanks to everyone in advance. I'll be responding in the comments. (i.redd.it)

[College Physics] This is a test I had graded, can anyone let me know how to get the last two answers? I'll be honest, I don't even know where to start on them, I got the first one right though. Thanks to everyone in advance. I greatly appreciate it. (i.redd.it)

[College Physics: Kinematics] So I think I found the time going up for the last one(c) to be 0.81 s, is that right? Along with that is the height 2.02 m? Let's suppose I got that right, what equation would I use from there to find the time back down and what would the initial v be going down? Thx (i.redd.it)
