Answer:
The answer to your question is SA = 1244.64 cm² ≈ 1245 cm²
Explanation:
Formula
SA = 2B + PH
Process
1.- Calculate B
B = Perimeter x 6.93/ 2
B = (8 x 6) x 6.93 / 2
B = 166.32 cm²
2.- Calculate 2B
2B = 2(166.32)
= 332.64 cm²
3.- Calculate PH
P = perimeter
P = 8 x 6
= 48 cm
PH = 48 x 19
PH = 912 cm²
4.- Calculate SA
SA = 332.64 + 912
SA = 1244.64 cm²
