Calculate circumference. You can do the math mentally with area & perimeter,but circumference is much more complex
Answer:
To measure EBC colour, the light absorption is detected at 430 nm (MEBAK 2.16. 2 respectively EBC 9.4). ... Then the absorption will be measured in a 10mm cuvette. The sample will be diluted until the absorption is less than 2 Extinction units (E430). EBC colour = E430 x 25 x dilution factor.

Answer:
82.8 in²
Step-by-step explanation:
The surface area a triangular based pyramid :
Base area + 1/2(perimeter * slant height)
Base = 8 inches ; Slant height = 4.6 inches ; altitude of base measure = 6.9 inches
Base area of triangle :
1/2 * base * height
1/2 * 8 * 6.9
4 * 6.9
Base area = 27.6 in²
The perimeter, P = sum of sides ; (s1 + s2 + s3
P = 8 + 8 + 8 = 24 in
Hence,
Surface area = 27.6 in² + 1/2(24*4.6)
Surface area = 27.6 in² + (12 * 4.6) in²
Surface area = (27.6 + 55.2)
Surface area = 82.8 in²
