• Lmetal in = x + 25
• Wmetal in = x
• 4 cut squares = 5 by 5 in
• Vfolded box = L * W * H
• Vfolded box = (x + 15) * (x - 10) * (5) = 3,000 cu in
• Afolded box base = (x + 15) * (x - 10) = 600 sq in
• 600 = (x + 15) * (x - 10)
• 600 = x^2 - 10x + 15x - 150
• 750 = x^2 + 5x
• x = 25 in

• Therefore original dimensions are:
-Lmetal = (25 + 25) = 50 in
-Wmetal = (25) = 25 in
