[see attachment]

Answer 1

5

Answer 2

how would you get the surface area of a rectangular closed box?

Answer 3

how would you get the volume?

Answer 4

great work irish boy...

Answer 5

@MCJones9879 if you want to learn how to do this, answer those two questions

Answer 6

use l and w ...

Answer 7

surface area = 2xy + 2xz+ 2yz

Answer 8

Is 5 supposed to be the answer?

Answer 9

no idea

Answer 10

so 2lw+2lh+2wh

Answer 11

and volume?

Answer 12

x*y*z

Answer 13

or l*w*h

Answer 14

hmm did it say it had a square bottom or side?

Answer 15

no

Answer 16

is this multi variable calculus?

Answer 17

ok solve for any variable in the volume equation and put it back into the area equation

Answer 18

then find the partial with respect to x, and then with respect to y

Answer 19

or what ever two variables you have.

Answer 20

2lw+2lh+2wh
lwh=125 --> l = 125/(wh)
put this into equation 1
2(125/(wh))w+2(125/(wh))h+2wh

Answer 21

are you with me?

Answer 22

250/h+250/w+2wh = 250h^(-1) + 250w^(-1)+2wh

Answer 23

partial with respect to h
-250/h^2+2w
wrtw
-250/w^2+2h

Answer 24

@MCJones9879 tell me when you would like to continue not wasting my time.:)
