1 Let its height be 12x and its width be 5x2 If: (2*12x*5x)+(2*12x*30)+(2*30) = 2520 sq cm3 Then: 120x2+720x+300x = 25204 And so: 120x2+1020x = 2520 => 120x2+1020x-2520 = 05 Solving the above quadratic equation gives x a positive value of 26 Therefore: height is 12*2 = 24 cm and width is 5*2 = 10 cm7 Volume: 24*10*30 = 7200 cubic cm8 Check: (2*24*10)+(2*24*30)+(2*10*30) = 2520 square cm
