Answer 2

Answer:

1716

Step-by-step explanation:

13 x 12 = 13 x (10 + 2)

= 13 x 10 + 13 x 2

= 130 + 26

= 156

13 x 12 x 11 = 156 x 11

= 156 x (10 + 1)

= 156 x 10 + 156

= 1560 + 156

= 1716

OR

11 = 12 - 1

13 = 12 + 1

11 x 12 x 13 = (12 - 1) x 12 x (12 + 1)

= (12 + 1) x (12 - 1) x 12

= ($12^{2}$ - 1) x 12

= (144 - 1) x 12

= 143 x 12

= 143 x (10 + 2)

= 143 x 10 + 143 x 2

= 1430 + 286

= 1716
