You can't. You'd need to know density and height of rod.
First of all we need to define the cross sectional area of the rod. If it is a cylinder rod we would use pi * r^2, Do this metrically to make things easy (metres). next we times that by a ft (in metric it is 30cm) so do: cross sectional area * 0.3m. this is the volume of the steel per foot. now find out the weight per cubic cm (density) and multiply them. To find mass of a material you need to weigh it, or times its relative atomic mass by the number of moles. You'll have to find the density of your steel as you havn't specified what kind and there isn't a 'pure' steel as its an alloy.
To find the perimeter you add and to find the area we multiply.
To find the relationship in width and area you can use the formula area/length = width. To find the area of a room you multiple the length by the width.
to find the surface area you have to first find the area of each part then add the areas together.
You can find a good rod on route 209 or you can find a super rod in the Fight Area.
To find the area of a rod, you need to know its shape. If the rod is cylindrical, you can calculate the surface area using the formula for the lateral surface area of a cylinder: 2πr * h, where r is the radius and h is the height of the cylinder. If the rod has a different shape, you will need to use the appropriate formula for that shape to find its area.
You can get it from a trade, the GTS, or find it possibly in the waters between the Fight Area, the Resort Area, and the Rest Area. You can find tentacool by just surfing just about anywhere. Or, using a good rod or old rod.
In the fight area.
Use a good rod at an area where you can find wailmer it may take awhile but you can get it.
You can get it from a fisherman at the fight area.
After beating the Elite Four, you can access the Fight Area, and there is a fisherman there who will give you the super rod.
there is no great god how ever there is a super rod u get on the fight area and theres a good rod that u get off a fishing rod hope that helped there is no great god how ever there is a super rod u get on the fight area and theres a good rod that u get off a fishing rod hope that helped
Find a fisherman in the Fight Area It is at northwest area (top left)
In the fight area. Beat the elete4 and then fly to snowpoint city and head to the sailor. in the fight area head north if you see a fisher man talk to him and then you get a super rod!
Very rarely if you use a super rod in the central area and Area 1 of the safari zone you can find dragonair.
you have to complete your sinnoh pokedex.then go to the battle area,then go up and talk to a fisherman and he'll give you the super rod
