To find the temperature in degrees Celsius using the given formula \( c = n^3 + 4 \), where \( n \) is the number of cricket chirps, we can substitute \( n \) with the number of chirps Charlie counted.
Charlie counted 51 chirps, so we substitute \( n = 51 \):
\[ c = 51^3 + 4 \]
First, calculate \( 51^3 \):
\[ 51^3 = 51 \times 51 \times 51 = 132651 \]
Then, add 4:
\[ c = 132651 + 4 = 132655 \]
So, the temperature in degrees Celsius is:
\[ 132655 , °C \]
Therefore, the answer is:
132655 °C
