Answer: 10 cubes are unseen in thes figure.
How many cubes are there in the given figure?
Total number of cubes = 14+14+8+8=44.
How many of the cubes have at least 2 faces painted?
Number of smaller cubes have at least two coloured face = Number of cubes present at 8 edge + Number of cubes present at 4 corner = 12 + 8 = 20. Was this answer helpful?
How many cubes are unseen in the figure?
Correct Option: A
10 cubes are seen in the figure. So, five cubes are unseen in the figure.
How do you find the number of cubes?
Correct Option: C
Total number of cubes = 6 × 6 × 4 = 144.
How many cubes in the third layer have at least two coloured faces each a 7 B 8 C 9 D 10?
Explanation: 64 and 64 cubes of both types of cubes are such who have at least two coloured faces red each. Therefore, total number of the required cubes is 128.
How many cubes are without any Colour?
Therefore all 64 smaller cubes have atleast one face exposed. Since all the sides of the two pieces are painted (either red and green), no small cube has any side which is not coloured. Hence, option 4 is the correct answer.
How do you solve the painted cube question?
10 cubes on each of those edges will have 1 side painted. Therefore, total cubes with 1 side painted= 5*100 + 4*10 = 540 cubes. According to the formula, cubes with no side painted= (12-2) 3= 1000. So, total number of unpainted cubes= 1000+100=1100.

What is a cube number example?
A cube number is the result when a number has been multiplied by itself twice. The symbol for cubed is 3. For example, 8 is a cube number because it’s 2 x 2 x 2 (2 multiplied by itself twice); this is also written as 23 (“two cubed”). Another example of a cube number is 27 because it’s 33 (3 x 3 x 3, or “three cubed”).
What are the first 10 cube numbers?
What are first ten perfect cube numbers? The first ten cube numbers are 1, 8, 27, 64, 125, 216, 343, 512, 729 and 1000.
How many smaller cubes have at least one surface painted with green Colour A 8 B 24 C 32 D 56?
So, there are 32 smaller cubes which have at least one of their faces green.
How many smaller cubes will have no surface painted a 0 B 4 C 8 D 16?
Number of smaller cubes having no surface painted =(n−2)3×6=(2)3=8.
How many smaller cubes have less than three surfaces painted a 8 B 24 C 28 D 48?
So the number of cubes having less than 3 faces painted = 24 + 24 = 48.
How many small cubes are there whose no faces are coloured *?
= 8. Was this answer helpful?
What is the number of cubes with only one face coloured?
Since all the sides of the two pieces are painted (either red and green). 8 smaller cubes in each piece which have one face painted. Hence, “16” is the correct answer. Stay updated with the Logical Reasoning questions & answers with Testbook.
How many small cubes will be there with no red paint at all?
There will be only one such cube with no paint at all. This cube is the one which has no face displayed in the initial big cube.
What is the cube formula?
x 3 = x × x × x. In algebra, cube refers to a number raised to the power 3. However, the meaning of cube is different in geometry, i.e. cube is a 3d shape with equal measure of edges and all the faces are squares.
How do you cube 7?
The cube root of 7 is the number which when multiplied by itself three times gives the product as 7. The number 7 is prime. Therefore, the cube root of 7 = ∛7 = 1.9129.
What is the square and cube of 7?
Squares and Cubes table
| Squares (n2) | Cubes (n3) | |
|---|---|---|
| 12 = 1 | 262 = 676 | 13 = 1 |
| 52 = 25 | 302 = 900 | 53 = 125 |
| 62 = 36 | 312 = 961 | 63 = 216 |
| 72 = 49 | 322 = 1024 | 73 = 343 |
What are all the possible perfect cubes modulo 7?
Because 7 is prime, either n≡0, n3≡1 or n3≡−1, so the only possible cubic residues modulo 7 are −1,0,1. These are all possible, as they are the residues of (−1)3,03,13.
