Final answer:
The total number of legs on 3 lambs is 12.
Step-by-step explanation:
To find the total number of legs on 3 lambs, we can multiply the number of lambs by the number of legs each lamb has. In this case, there are 3 lambs and each lamb has 4 legs. So, the total number of legs would be 3 multiplied by 4, which equals 12 legs.
