How to cast an object to Type?

I want to cast an object to a type that a System.Type object defines. I only know the object and the Type as inputs, I can't add type parameters.

void Test()
{
    object obj = 3;
    Type type = typeof(int);

    int number = Cast(obj, type);

    Console.WriteLine($"{number}, {number.GetType()}"); // Should output "3, System.Int32"
}

I can't change the inputs
??? Cast(object obj, Type type)
{
    // return the obj casted to type, but how?
}

I guess there's a way to solve it using reflection but I couldn't find anything like this.
