The figure below is the two-dimensional net of a rectangular prism. what is the surface area of the prism it can be folded to form? show your work. 8 square units 20 square units 24 square units 28 square units

See the picture with letters attached to better understand the problem

we know that
surface area=area A +area B+area C+area D+area E+area F

area A=area F
area B=area area D
area C=area E
so
surface area=[2*1]+[4*2]+[4*1]+[4*2]+[4*1]+[2*1]----> 28 units²

the answer is
28 units²
