ANSWER: 1

5

A solid cube of each side 8 cm, has been painted red, blue and black on pairs of opposite faces. It is then cut into cubical blocks of each side 2 cm.

How many cubes have no face painted?

a

0

b

4

c

8

d

12

correct answer c

Cubes have no face painted = Inner Cubes (No Colour): We can find out the total number of cubes without any colour on any side (inner cube) with this formula: (X-2)^3

Implementation of formula: X = 4

(4-2)^3 = 2^3 = 8

6

A solid cube of each side 8 cm, has been painted red, blue and black on pairs of opposite faces. It is then cut into cubical blocks of each side 2 cm.

How many cubes have only one face painted?

a

8

b

16

c

24

d

28

correct answer c

Cubes have only one face painted = Central cubes : In middle of faces & has only one coloured side.

We can find out the total number of cubes with singe colour on any side with this formula: 6(X-2)^2

Implementation of formula: X = 4

6(4-2)^2 = 6(2)^2 = 24

7

A solid cube of each side 8 cm, has been painted red, blue and black on pairs of opposite faces. It is then cut into cubical blocks of each side 2 cm.

How many cubes have only two faces painted?

a

8

b

16

c

20

d

24

correct answer d

Cubes have only two faces painted = Middle Cubes: In middle of edges and have two coloured sides.

We can find out the total number of cubes with singe colour on any side with this formula: 12(X-2)

Implementation of formula: X = 4

12(4-2) = 12(2) = 24

8

A solid cube of each side 8 cm, has been painted red, blue and black on pairs of opposite faces. It is then cut into cubical blocks of each side 2 cm.

How many cubes have only three faces painted?

a

0

b

4

c

6

d

8

correct answer d

Cubes have only three faces painted = Corner cubes : Cubes on corners and have three coloured sides.

A cube can have only 8 cut-corner cubes with colours on three sides. Hence answer will be always the same = 8.

9

A solid cube of each side 8 cm, has been painted red, blue and black on pairs of opposite faces. It is then cut into cubical blocks of each side 2 cm.

How many cubes have three faces painted with different colours?

a

0

b

4

c

8

d

12

correct answer c

Cubes have three faces painted = Corner cubes : Cubes on corners and have three coloured sides.

A cube can have only 8 cut-corner cubes with colours on three sides. Hence answer will be always the same = 8.

10

A solid cube of each side 8 cm, has been painted red, blue and black on pairs of opposite faces. It is then cut into cubical blocks of each side 2 cm.

How many cubes have two faces painted red and black and all other faces unpainted?

a

4

b

8

c

16

d

32

correct answer a

Cubes have two faces painted red and black and all other faces unpainted = 2+2 = 4
