Let’s solve each question one by one. Remember, the
cube of a number means multiplying that number by itself
three times.
For example:
Cube of 2 = 2 × 2 × 2 = 8

(1) The cube of 0 is:
0 × 0 × 0 =
0 → Answer:
(A) 0
(2) The cube of 1 is:
1 × 1 × 1 =
1 → Answer:
(B) 1
(3) The cube of 2 is:
2 × 2 × 2 = 4 × 2 =
8 → Answer:
(B) 8
(4) The cube of 3 is:
3 × 3 × 3 = 9 × 3 =
27 → Answer:
C) 27
(5) The cube of 4 is:
4 × 4 × 4 = 16 × 4 =
64 → Answer:
A) 64
(6) The cube of 5 is:
5 × 5 × 5 = 25 × 5 =
125 → Answer:
(D) 125
(7) The cube of 6 is:
6 × 6 × 6 = 36 × 6 =
216 → Answer:
(A) 216
(8) The cube of 10 is:
10 × 10 × 10 = 100 × 10 =
1000 → Answer:
(C) 1000
(9) The cube of 12 is:
12 × 12 = 144; then 144 × 12
Let’s calculate:
144 × 10 = 1440
144 × 2 = 288
Add them: 1440 + 288 =
1728 → Answer:
(B) 1728
(10) The cube of 15 is:
15 × 15 = 225; then 225 × 15
225 × 10 = 2250
225 × 5 = 1125
Add: 2250 + 1125 =
3375 → Answer:
(A) 3375
(11) The cube of 20 is:
20 × 20 = 400; then 400 × 20 =
8000 → Answer:
(A) 8000
(12) The cube of 25 is:
25 × 25 = 625; then 625 × 25
Break it down:
625 × 20 = 12,500
625 × 5 = 3,125
Add: 12,500 + 3,125 =
15,625 → Answer:
(B) 15625
