Answer:
cubeVolume = toThePowerOf(cubeSide, 3)
Explanation:
The function toThePowerOf, receives two int arguments say, a and b, where a is the first argument and b is the second argument as follows:
toThePowerOf(a,b)
The function returns the first argument(a) raised to the power of the second argument (b) i.e a ^ b as follows:
toThePowerOf(a, b){
return a^b
}
In the call to the function, the first argument a, is replaced with the variable cubeSide and the second argument b is replaced with the value 3.
Hence, the returned result becomes cubeSide ^ 3 which is then stored in a variable cubeVolume as follows:
cubeVolume = toThePowerOf(cubeSide, 3)
