根据main函数，类名应该是form

#include <iostream>
using namespace std;
class form
{
private:
    int m_length;
    int m_width;
    int m_height;
    int m_squareLength;
public:
    void inputCuboid()
    {
        cin>>m_length;
        cin>>m_width;
        cin>>m_height;
    }
    int getCuboidArea()
    {
        return 2*(m_length*m_width+m_length*m_height + m_width*m_height);
    }
    int getSquareArea()
    {
        return 6*m_squareLength * m_squareLength;
    }
    int getSquareSide()
    {
        m_squareLength = 1;
        while(getSquareArea() < getCuboidArea())
            m_squareLength++;
        return m_squareLength;
    }
};

int main()
{
    form oneform;
    oneform.inputCuboid();
    cout<<oneform.getSquareSide()<<endl;
    return 0;
}
