Answer:
Step-by-step explanation:
We want to find the surface area of this prism.
There are 6 faces on a rectangular prism, and the opposite faces will have the same dimensions.
2 4 by 3 faces - 2*12=24
2 3 by 5 faces - 2*15=30
2 4 by 5 faces - 2*20=40
24+30+40=24+70=94 cm^2
Because completementary angles add up to 180 degrees (angle 3 and angle 4)
and interior angles of a triangle will also add up to 180 degrees
if you compare these two facts, then angle 4 equals the 2 non adjacent interior angles
