Evaluate the following and write which number is the cube of which other number.

(1) 3³ (2) 7³

(3) 4³ (4) 9³

(5) 11³ (6) 15³

(1) The cube of 3 can be written as follows:

⟹ 3 × 3 × 3

⟹ 9 × 3

= 27

Hence 3³ = 27.

(2) The cube of 7 can be written as follows:

⟹ 7 × 7 × 7

⟹ 49 × 7

= 343

Hence 7³ = 343.

(3) The cube of 4 can be written as follows:

⟹ 4 × 4 × 4

⟹ 16 × 4

= 64

Hence 4³ = 64.

(4) The cube of 9 can be written as follows:

⟹ 9 × 9 × 9

⟹ 81 × 9

= 729

Hence 9³ = 729.

(5) The cube of 11 can be written as follows:

⟹ 11 × 11 × 11

⟹ 121 × 11

= 1331

Hence 11³ = 1331.

(6) The cube of 15 can be written as follows:

⟹ 15 × 15 × 15

⟹ 225 × 15

= 3375

Hence 15³ = 3375.
