Okkk so Surface area is the area of all the surfaces added together, this triangular prism consists of
2 triangles and 3 rectangles

To find the area of a triangle you do base x height divided by 2

To find the area of a rectangle
Length x width

Sooooo

Side 1= triangle
12x16/2: 96

Side 2= triangle
12x16/2: 96

Side 3= rectangle
12x10: 120

Side 4= rectangle
16x10: 160

Side 5= rectangle
10x20: 200

To find the SURFACE AREA
add them all together

96+96+120+160+200= 672 centimeters squared

Or square centimeters

SURFACE AREA UNITS is always squared so like square meters, centimeters, millimeters etc
