Using a cereal box, the dimensions are 8 inches wide by 12 1/8 inches tall by 1 3/4 inches deep.

Parallel to the base it would be a rectangle 8 inches x 1 3/4 inches.

Surface area = 2 x (12 1/8 x 8) + 2 x (8 x 1 3/4) + 2 x ( 12 1/8 x 1 3/4) = 194 + 28 + 42 7/16 = 264 7/16 square inches.

Surface area if scaled up by a factor of 10:

10^2 = 100

264 7/16 x 100 = 26,443 3/4 square inches.

Volume =  8 x 12 1/8 x 1 3/4 = 169 3/4 cubic inches.

Volume scales down by 1/3:

1/3^3 = 1/27

169 3/4 x 1/27 = 6 31/108 cubic inches.
