Answer:
Area of the right rectangular prism is 22 in² .
Explanation:
Formula
Surface area of a right rectangular prism = 2 (Length × Breadth + Breadth × Height + Height × Length)
As given the diagram
Length = 3 in
Breadth = 1 in
Height = 2 in
Put all the values in the formula
Surface area of a right rectangular prism = 2 × (3 × 1 + 1 × 2 + 2 × 3)
= 2 × (3 + 2 + 6)
= 2 × 11
= 22 in²
Therefore the area of the right rectangular prism is 22 in² .
