Given that:

Cubical with sides 15.8 cm

Thickness = 3 cm

Solutions:

External volume = 15.8 cm x 15.8 cm x 15.8 cm

                           = 3944.312 cm³

Internal Volume = (15.8 - 3) cm x (15.8 - 3) cm x (15.8 - 3) cm

                           = 2097.152 cm³

Wood needed = 3944.312 cm³ - 2097.152 cm³

                         = 1847.16 cm³

1847.16 cm³ of wood is needed to make that cubical chalk box.
