A box has a volume of 7500 cm3 and a surface area of 2600 cm2. What are length, width, and height of the box?
Answered by Mgraph
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

30 x 20 x 10 doesn't fit the surface area

I did not understand
Answered by Andrew
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
