If you assume length to be a subjective term generally referring to the dimension with the longest measurement, then for this object W (width) is equivalent to length, in which case you may like to think of D (depth) was width instead.
It depends on your perspective in relation to this object. Lets say this object is a (extendable) desk and the units are inches - if you are facing the desk, you will see it is 29.5" high (perhaps roughly hip height). Since the dimension which measures 39" extends away from you, the most appropriate label is depth.
W X D X H is the usual way to describe the dimensions of an item of furniture or similar. W X L (X H) is normally used for more tranportable objects for which your perspective would be changing. For example, a mail package.
area = length x bredth new_area = (2 x length) x bredth = 2 x (length x bredth) = 2 x area → doubling the length, but leaving the bredth unchanged doubles the area. perimeter = 2 x (length + bredth) new_perinter = 2 x (2 x length + bredth) = 2 x (length + length + bredth) = 2 x length + 2 x (length + bredth) = 2 x length + perimeter → doubling the length, but leaving the bredth unchanged adds twice the original length (ie the new length of the rectange) to the perimter.
length x width x height or length x breadth x height
It depends on the length of x.It depends on the length of x.It depends on the length of x.It depends on the length of x.
The formula is: r2 x Pi x length (radius squared x 3.1416 x length). The result is expressed in cubic units.or this also worksdiameter x diameter x 0.7854 x length
You really should know how to answer that question.Volume = (length) x (width) x (height) .Length = (volume) / (width x height)Width = (volume) / (length x height)Height = (volume) / (length x width)
Volume = Length x Width x Depth
(length of side)2 X 6 [or (length of side) X (length of side) X 6]
Perimeter: Add the length of the four sides. Area: Multiply length x width.
It doesn't really matter, but most people usually write length x width.
[Power] = energy / time = force x length / time = mass x length/time2 x length/time= mass x length2/time3
The volume of a cube (where all sides are equal length) is the length3. In other words length x length x length. Your answer is 20 x 20 x 20 = 8,000cm3
The term cubic applies to cubes, cuboids, and other parallelograms, which have 3 dimensions - length, width, and height for example. To find the volume, multiply the length times the width times the height in any consistent units. The formula is L x W x H.
