[問題] double point 指標的位置

請問一下，我宣告一個5*3的double point int **X
利用監看式觀察X[1]的address 並將他轉成int
也就是觀看(int)X[1] 和(int)X[2]
結果(int)X[1]=3878792 (int)X[2]=3878864
這兩個值差了72 請問這個72是怎麼來的?
環境是在VC2005底下
程式碼如下；
int **X,i,different;
X=(int**)malloc(5*sizeof(int*));
for(i=0;i<5;i++)
{
X[i]=(int*)malloc(3*sizeof(int*));
}
different=(int)X[2]-(int)X[1];
________________________________________________
different=72 why?
