length x width x height
Volume = Length * Width * Height
the three dimensions needed to find the area of a rectangular solid object are: Height, Length and Width.
To find the volume of a rectangular object, you multiply its length, width, and height. To find the mass, you would then multiply the volume by the object's density, which is typically provided in grams per cubic centimeter.
This is clearly lifted from some test paper, omitting the vital diagram. The volume of a rectangular prism is the area of the base multiplied by the height. Same for a cube.
If it is a cube (basically a square) or a rectangular prism multiply the top, the length, and the base.
Volume of any prism = cross-section area times 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.
length, width and height (:
Height x Weight x Height
Height x Weight x Height
Height x Weight x Height
Yes, density is defined as the mass of an object divided by its volume. So, to find the density of an object, you would divide its mass by its volume.
