}

public function execute()
{
     $orderId = 5;  //PASS YOUR ORDER ID HERE
     $order = $this->orderFactory->create()->load($orderId);
     $orderItems = $order->getAllItems();
     $total_qty = 0;
     foreach ($orderItems as $item)
     {
          $total_qty = $total_qty + $item->getQtyOrdered();
     }
     return $total_qty;
}

Method 2 : Using Object Manager (Not Recommended Method)

$order_id = 5;  //PASS YOUR ORDER ID HERE
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $objectManager->create('Magento\Sales\Model\Order')->load($order_id);
$orderItems = $order->getAllItems();
$total_qty = 0;
foreach ($orderItems as $item)
{
   $total_qty = $total_qty + $item->getQtyOrdered();
}
 
echo $total_qty;
