Lynn Ann is designing a rappers who made new dark chocolate candy that her company is going to sell the candy bar is a triangular prison the dimension of the candy bar are shown in the 6.97.47.49.95.1 which measurement is closest to the total surface area of the candy bar in square centimeters
To find the total surface area of the candy bar, you need to calculate the sum of each face's area.
Given that the dimensions of the candy bar are shown as 6.9 x 7.4 x 9.5 cm, you can calculate the surface area as follows:
Face 1 (base): 6.9 cm x 7.4 cm = 51.06 cm²
Face 2: 6.9 cm x 9.5 cm = 65.55 cm²
Face 3: 7.4 cm x 9.5 cm = 70.3 cm²
Triangle faces: (0.5 x 6.9 cm x 9.5 cm) + (0.5 x 6.9 cm x 7.4 cm) = 48.725 cm² + 25.485 cm² = 74.21 cm²
Total surface area ≈ 51.06 cm² + 65.55 cm² + 70.3 cm² + 74.21 cm² = 261.12 cm²
Therefore, the measurement closest to the total surface area of the candy bar is 261.12 cm².
