2 x 220 = 440

440 + 128 = 568 cookies (maximum)

The table is 50 by 33.

So to lay the papers to ensure maximum coverage would be to use
the 6 cm to cover the longer side, 50...

Hence it covers up to 48cm with 8 pieces.

The 33cm side covered by 8cm side will need 4 pieces of paper. (covered up to 32cm)

No. of pieces of coloured paper required = 8 x 4 = 32

Hi

Use 6cm side to cover 50 cm up to 42 cm ie 7 pieces, with 8cm covering the 33cm side up to 32 cm ie 4 pieces --> total 4 x 7 = 28 pieces.

now, we are left with 8cm x 33cm... use 6cm side to cover the 33 cm side up to 30 cm ie 5 pieces

total 28 + 5 = 33 pieces of 8 x 6 cm
