Answer:
 62 square units
Step-by-step explanation:
The area of a rectangular prism is the sum of the areas of its six faces. Opposite faces have the same area, so it is the sum of 3 pairs of faces. The area of one face of each pair is the product of the dimensions of that face. Those three areas are ...
 • L·W
 • W·H
 • H·L
so the total surface area is ...
 A = 2(LW +WH +HL)
For hand calculation, this can be simplified a bit to ...
 A = 2(LW +H(L+W)) . . . . . requires one less multiplication
For your prism, the area is ...
 A = 2(5·2 + 3(5+2)) = 2(10 +21) = 62 . . . square units
 
        
             
        
        
        
Answer: True, True, True
Step-by-step explanation:
A. True. Angles B and C are congruent, and since B' is congruent to B, by the transitive property, C is congruent to B', and thus has the same measure.
B. True. AB>BC, and the rigid motions won't change the side lengths.
C. True for the same reason in B.
