It is length * breadth * height.
conclusion
Yes. It doesnt have to be a irregular even though sometimes it is easier just to do the math... for a rectangular object. l x w x h= volume
Water Displacement Method?
The length times the width times the height.

conclusion
It looks like you meant width or thickness. This is the formula to calculate volume or capacity of a rectangular prism (a box).
It all depends upon the shape of the object. For example, the volume of a rectangular prism is lengthxwidthxheight. For an irregular shaped object, one strategy is to immerse the object into a measured amount of water, then measure what is the total volume of water plus object, and subtract the original volume of water.

Is 0.08m the length or width of this rectangular aquarium? Need both measurements to calculate the volume of water, unless this is a SQUARE shaped aquarium.
Rectangular
No, a rectangular prism is a 3D object with rectangular sides and a shape with 3 or more edges on both ends. A dollar bill (or any other similar piece of paper) is a 2D rectangle.
Rectangular prism
Not in the sense of a six-sided cube or rectangular object. It is a relatively contained area that is well-defined by anatomic structures, however.
