**Answer:**

**Step-by-step explanation:**

**Answer:**

The replicas will have a surface area of 3 m2, 2.4 m2 and 2 m2 respectively.

**Step-by-step explanation:**

Given that a pyramid art installation has a surface area of 24 m2, and an artist creates replicas with scale factors of 1/8, 1/10, and 1/12, to determine what is the surface area of each replica, the following calculation has to be done:

24 x 1/8 = 3

24 x 1/10 = 2.4

24 x 1/12 = 2

Therefore, the replicas will have a surface area of 3 m2, 2.4 m2 and 2 m2 respectively.
