Help I am so confused on what to do with theses steps to get the answer.

Step 1 convert all the dimensions of the box from cm to m


Step 2 calculate the maximum buoyant force if the box was completely submerged. Fb = pfluid V g

Step 3 calculate the Fg of the box Fg = mg

Step 4 Subtract the Fg from the Fb to get the Force of gravity from extra mass

Step 5. Use the Fg from extra mass =mg equation to solve for mass. Using
