Submerge it in water and measure how much the water rises.
Fill it with water then empty it into a graduated beaker to measure it.
Water Displacement
by measuring the amount of water it displaces
Displacement. You have a beaker with a known amount of water. Put the object in. Subtract the current volume minus the starting volume (of water). The difference is the amount of water displaced, telling you the volume of the object.
To determine the density of an object, you need its mass and volume. If the object is oddly shaped, you can determine its volume by measuring the volume of water displaced when thee object is submerged in a container of water.
Contours lines are oddly shaped because it goes according to how it is shaped.
It is not at all skewed. As to oddly shaped, it depends on your expectations.
If the object is oddly or irregularly shaped, then it's much easier to measureits volume with the graduated cylinder than with the ruler. But the volumeis the same no matter how it's measured. If the results are not the same,then at least one and possibly both measurements were done wrong.
Contour lines are oddly shaped because it goes according to whatever its up aganist.

This could be a relatively easy volume question or not. First you have to figure the volume of the box. This is Height x Length x Width. Then you find the volume of the object you want to put in the box. If they are rectangular the formula is the same. If they are spherical the equation is 4/3 Pi R^3. If they are oddly shaped the equation is more difficult or you must measure the volume by another means such as water displacement. Once you have the volume of the box and the volume of what you want to put in the box you just divide the later into the former and you have how many should fit in the box. Now an assumption of this solution assumes all the "free" space is occupied by the object you put in the box. If your solution needs an exact number in real life you have to figure out the amount of "free" space that is lost with each object placed in the box and add that into the calculation.
Divide your oddly shaped room into smaller standard shapes. Calculate each smaller shape's area then add all of your answers together.
