my ipad wont open and heating up

Hello, I have an iPad 6th (2018) that I haven't opened my yesternight, I still used it yesterday morning. I left it to charge then when I came back, it's screen turned black and it won't turn on, I tried force restarting it (pressing the power and home button) multiple times but nothing worked. I left it overnight, thinking it would fix the issue, but I discovered that it's now heating on it's right side, and it still wouldn't open. What should I do?
