Answer:
Option (D)
Step-by-step explanation:
Surface area of a square pyramid is determined from the formula,
Surface area = Area of the square base + 4(Area of one lateral triangular side)
Area of the base = (Side)²
                             = 8²
                             = 64 cm²
Area of one lateral triangle = 
                                              = 
                                              = 32 cm²
Therefore, surface area of the square pyramid = 64 + 4(32)
                                                                               = 64 + 128
                                                                               = 192 cm²
Therefore, Option (D) will be the correct option.

No, because all sides are not congruent. The answer is B.
        
                    
             
        
        
        
First you need to divide 125 / 25 which is 5 then you do subtraction 21 x 5 which is 105, then you subtract again 125 - 105 which is 20, 20 light bulbs will be broken. Or you could have just multiplied 5 by 4 which is the amount of light bulbs that were broken which is a lot easier...
