Remember that

The surface area of the given figure, is equal to the area of all its six faces

step 1

Find out the area of the base

The base is a rectangle of 19 in x 22 in

[tex]A_1=19*22=418\text{ in}^2[/tex]

step 2

Find out the area of the top

The top is a rectangle of 13 in x 22 in

[tex]A_2=13*22=286\text{ in}^2[/tex]

step 3

Find out the area of the two trapezoidal faces

[tex]A_{3-4}=2[\frac{1}{2}(19+13)(14)]=448\text{ in}^2[/tex]

step 4

Find out the area of the two lateral rectangular faces

[tex]A_{5-6}=2[22*16]=704\text{ in}^2[/tex]

therefore

The surface area is equal to

SA=418+286+448+704

SA=1,856 in2
