What is the surface area of this right rectangular prism? enter your answer in the box.

Area of the  right rectangular prism is 22 in² .

Step-by-step 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 .

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
