Which expression represents the total surface area, in square centimeters, of the square pyramid? A square pyramid. The square base has side lengths of 8.2 centimeters. The triangular sides have a height of 10.3 centimeters.

Total surface area of the pyramid is 236.16cm² and the expression is

2bs + s²

Step-by-step explanation:

Total surface area of a square pyramid is expressed as;

TSA = 2bs + Base Area

b is the side length  of the base = 8.2cm

s is the slant height of the triangular side = 10.3cm

Base area = s²

Base area = 8.2²

Base area = 67.24cm²

TSA = 2(8.2)(10.3)+67.24

TSA = 168.92+67.24

TSA = 236.16cm²

Hence the total surface area of the pyramid is 236.16cm² and the expression is 2bs + s²

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
