Answer 1

Answer:

11335 cm square

Step-by-step explanation:

let length = 79cm , breadth = 25cm & height = 45cm

area of base = length*breadth = 79*25=1975cm square

area of back and side face = 2*45*79 + 2*45*25 = 7110+2250 = 9360cm square

total area of paper required to cover base ,side faces , front and back faces = 9360+1975 = 11335 cm square
