Passing two dimensional array of strings to function?

I am trying to send this array to the function sortByLength.

The function prototype is

sortByLength(char *words[],int * lengths, const int size);

Here is the rest of my code up to where I try to pass it to the function:

#include <stdio.h>
#include "task2.h"
#define SIZE 3

int main(void)
{
    int i;
    int lengths[SIZE] = {3, 4, 6};
    char words[][20] = {"Sun", "Rain", "Cloudy"};

    sortByLength(words[][20],lengths,SIZE);

    return 0;
}

The prototype 

sortByLength(char *words[],int * lengths, const int size);

is equivalent to 

sortByLength(char **words,int * lengths, const int size);

words[][20] will converted to pointer to array of 20 chars when passed to a function. char ** and char (*)[20] are incompatible types. Change function prototype to 

sortByLength(char (*words)[20], int *lengths, const int size);
