Answer : C
Explanation
It is impossible to get four varnished faces out of a big cube. Hence answer is zero.
Answer : D
Explanation
Tiny cubes having only two faces varnished = (x - 2) × number of edges = (10 - 2) × 12 = 8 × 12 = 96. Hence option D is the answer.
Q 3 - Chicky has a cube whose each portion is of 9 cm. If she wants to cut tiny cubes of portion 3 cm each, then how many such cubes will be possible for her?
Answer : D
Explanation
Here x = (9/3) = 3
So number of cubes = 3 × 3 × 3 = 27. Hence option D is correct.
Q 4 - A big cube is segmented into tiny cubes and each portion of the tiny cubes are of equal length. The total number of tiny cubes formed is 64. Each portion of the tiny cubes is 3 cm. Find out the length of each portion of the original bigger cube
Answer : A
Explanation
Number of cubes = 64. Cube root of 64 is 4. So x = 4. By formula, portion of big cube = 4 × 3 = 12. Hence option A is correct.
Answer : C
Explanation
x = 6. So x - 2 = 6 - 2 = 4. 4 × 4 × 4 = 64.
Q 6 - A big cube whose all the corners are named as P, Q, R, S, T, U, V and W. Its each portion is of 50 cm in length. The cube is segmented into tiny cubes and length of the portion of each tiny cube is 2.5 cm. Then how many such cubes are possible?
Answer : D
Explanation
To find the number of tiny cubes, first we have to find x. So x = (50/2.5) = 20. So number of tiny cubes M = 20 × 20 × 20 = 8000. Hence option D is the answer.
Q 7 - Harry has a cube whose each portion is of 15 cm. If she wants to cut tiny cubes of portion 1.5 cm each, then how many such cubes will be possible for her?
Answer : C
Explanation
x = (15/1.5) = 10
So total number of cubes = 10 × 10 × 10 = 1000. Hence option C is correct.
Answer : D
Explanation
Tiny cubes having only two faces varnished = (x - 2) × number of edges = (8 - 2) × 12 = 6 × 12 = 72. Hence option D is the option.
Answer : D
Explanation
The answer is the number of corners available which is 8. Hence option D is the correct answer.
Answer : C
Explanation
Here x = 8. So x - 2 = 8 - 2 = 6. 6 × 6 × 6 = 216.
