The surface area is the sum of the area of the six sides...
A=2(xy+xz+yz)
A=2(8*3+8*5+3*5)

A=158 cm^2
A small box because you can buy 2 or more boxes for a less price
i hope this helped and if it didn’t.. sorry
8x-10y=-23
9x+10y=-16
(8x+9x)+(10y-10y)=(-23+(-16))
17x+0y=-39
x=-39/17
8(-39/17)-10y=-23
-312/17-10y=-23
-10y=-23+312/17
-10y=-79/17
y=79/170
First pick one that turns out to be a positive or negative
