Answer:

SA ==736^2

Without unit = 736^2

Explanation:

Start with base of a triangle face

Base = 12 Height = 8

1/2 x 12 x 8 = 48 cm^2 one side face surface area

48 x 2 = 96 cm^2 two side face surface area bold

----

Sides

10 x 20 = 200 cm^2 one side face surface area

200 x 2 = 400 cm^2 two side face surface area bold

-----

base 20 x 12 = 240 cm^2 single base. bold

Add up those values in bold = 240 + 400 + 96 =736 cm^2
