L*W*H=7500
2(L*W+L*H+W*H)=2600
This system has an infinite number of solutions and one of them is:
L=30, W=25, H=10
A box has a volume of 7500 cm3 and a surface area of 2600 cm2. What are length, width, and height of the box?

Thank you so much!
correct
30 x 20 x 10 doesn't fit the surface area
i needed this, thank you
I did not understand
for the whole numbers only one combination exists: 30 25 10
The way to solve it is to look at 7500, 00 at the end indicates that at least 2 numbers needs to end with 0 ;
simplest 10 750 (10 75) will result in incorrect SA
20 375 (75 5 ,15 25) will result in incorrect SA
30 250 (25 10) matches SA

What about surface area?
They said something about the surface area where is that?
