Answer:
The surface area of the right rectangular prism is, 22 square inches.
Step-by-step explanation:
Surface area of the right rectangular prism(A) is given by:
[tex]A =2(wl+hl+hw)[/tex] ....[1]
where,
w is the width
l is the length
h is the height of the right rectangular prism respectively.
As per the statement:
A rectangular prism with a length of 3 inches, a width of 1 inch, and a height of 2 inches
⇒[tex]l = 3[/tex] in., w = 1 in. and h = 2 inches.
Substitute these in [1] we have;
[tex]A =2(1(3)+2(3)+2(1))[/tex]
A = 2(11)
⇒[tex]A = 22 in^2[/tex]
Therefore, the surface area of the right rectangular prism is, 22 square inches.
