Description: Volume= (U+3)m3, where U is the third digit of the student number. In this case the student number is 1839996 and so the third digit is 9. So, Volume=(9+3)m3=12m3, The cost breakdown is given by: * Cost of the base and top is 8 Pounds/m2 * Cost of the front side is (10+Z)Pounds/m2= 16 Pounds/m2...
