To find the temperature in degrees Celsius (c) based on the number of cricket chirps (n), we can use the given formula:
\[ c = n^3 + 4 \]
In this case, Charlie counts 51 cricket chirps (n = 51).
Now, we can substitute 51 into the formula:
\[ c = 51^3 + 4 \]
First, calculate \( 51^3 \):
\[ 51^3 = 51 \times 51 \times 51 = 132651 \]
Now, we add 4:
\[ c = 132651 + 4 = 132655 \]
Therefore, the temperature in degrees Celsius is:
132655 °C.
