Answer:

• Surface area = 104 in.

Explanation:

We know that:

• Side lengths of rectangular prism: 2 in, 5 in, and 6 in.
• Surface area = Area of all faces

Solution:

• Surface area = 2(6 x 2) + 2(5 x 2) + 2(6 x 5)
• => Surface area = 2(12) + 2(10) + 2(30)
• => Surface area = 24 + 20 + 60
• => Surface area = 104 in.

Hence, the surface area of the rectangular prism is 104 in.
