length x width x height
the formula depends on the shape of the object
Density of an object is defined as (mass)/(volume).
Exactly the same as for a non-floating object. Finding the volume of a shape does not vary, (i.e it's always something along the lines of height*width*depth, or area of base *height. "Table" or "surface" is irrelevant, since if it not a variable in the formula). This is true whether the object is floating or not.
Height x Weight x Height
length x width x height
It depends completely on the object. The mirror has to be of at least half the height of the object. Otherwise there will be no image of the object on the mirror.
the formula depends on the shape of the object
it depends on height of object and distance of object from the mirror
It depends on the exact shape. For a square or rectangle, it would be length times width times height.
The distance between the object and mirror is 15 mm. The distance between the image and mirror is 15 mm. Therefore, the distance between the image and object is 15 mm plus 15 mm which equals 30 mm.
Density of an object is defined as (mass)/(volume).
The formula for finding the force of an object is F = ma. The "F" stands for force, "m" stands for mass and "a" is for acceleration. Force is the product of mass and acceleration.
