It looks like you meant width or thickness. This is the formula to calculate volume or capacity of a rectangular prism (a box).
Height (thickness or dept) Width Length
A rectangular prism has a volume that can be found by multiplying the object's length width and height. To obtain the mass one must also know the density of the object and multiply that by the volume.
-- Measure length, width, and height. -- Multiply (length) times (width) times (height). -- The result is the volume of the box-shaped object.
To find the volume of an object you must multiply the height by the width by the length. Expression:(HxWxL=Volume)
It is easiest to measure the length, breadth and height and multiply them together.
Length by height.Addition:About artworks it is always height by length.
-- measure the length, width, and height of the object -- multiply the three numbers together -- the answer is the volume of the object
measure with a ruler the length, width and height and multiply lxwxh
False on two counts. A rectangular shape is 2-dimensional and so can have no mass. If it is rectangular but has length, width and height then it is a cuboid object. Then, multiplying the length width and height will give the volume, not the mass.
This is the formula for volume:l x h x w( length x height x width )
Measure the three dimensions ( length, width and height) and multiply them together
The usual protocol for stating sizes is "height, width, and depth", but these are subjective descriptions based on the orientation of the measured object or space. Practically speaking, the two larger numbers of the set can be used as the height and width, and the smallest the thickness or depth.
