Answer 2

Answer:

8

Step-by-step explanation:

A cube of side four inch is painted red blue and black on the pairs of opposite faces. It is then cut into smaller cubes of side one inch each. How many cubes have one face red and one blue

Across the four edges where Red & Blue meets cube will have Red & Blue faces

as 4 inch Cube is cut into i inch cubes

so there will be 4 cube across each edge

so 4 * 4 = 16 Cubes Will have Red & Blue Faces

But cubes at 8 corners will have Black face as well so

out of these 16 cubes 8 cubes will be having Red , Blue & Black faces

So Cubes with only Red & Blue faces = 16 -8 = 8
