# Problems based on Cubes and Dice Question Figures and answers : Non Verbal

• Directions: (Questions 1 to 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.

1.

How many cubes have no face painted?

A.) 0
B.) 4
C.) 8
D.) 12

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 color on any side with this formula: 6(X-2)2
Implementation of formula: X = 4
6(4-2)2 = 6(2)2 = 24

2.

How many cubes have only one face painted?

A.) 8
B.) 16
C.) 24
D.) 28

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

3.

How many cubes have only two faces painted?

A.) 8
B.) 16
C.) 24
D.) 20

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

4.

How many cubes have only three faces painted?

A.) 0
B.) 4
C.) 6
D.) 8

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

5.

How many cubes have three faces painted with different colours?

A.) 0
B.) 4
C.) 12
D.) 8

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.

6.

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

A.) 0
B.) 8
C.) 12
D.) 14

Cubes have two faces painted red and black and all other faces unpainted = 4+4 = 8

7.

How many cubes have only one face painted red and all other faces unpainted?

A.) 0
B.) 14
C.) 12
D.) 8

Cubes have only one face painted red and all other faces unpainted = Central Cubes of Red Face = 4+4 = 8

8.

How many cubes have two faces painted black?

A.) 2
B.) 4
C.) 8
D.) None

None

9.

How many cubes have one face painted blue and one face painted red? (the other faces may be painted or unpainted?

A.) 16
B.) 14
C.) 8
D.) 0

Cubes have one face painted blue and one face painted red? (the other faces may be painted or unpainted = 4+4 = 8

10.

How many cubes are there in all?

A.) 64
B.) 56
C.) 40
D.) 32
