Respuesta :

Answer:

[tex]10800\ \text{cm}[/tex]

Step-by-step explanation:

l = Length = 11 cm

w = Width = 8 cm

h = Height = 8 cm

Perimeter of cardboard required for one box is

[tex]4(l+w+h)=4(11+8+8)\\ =108\ \text{cm}[/tex]

There are 100 gifts to pack so the total amount of cardboard needed would be

[tex]108\times 100=10800\ \text{cm}[/tex]

So, the minimum amount of cardboard Cathy needs to package all the gifts is [tex]10800\ \text{cm}[/tex].
