width x height x depth
or
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.
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
If you know the density of the rectangular body you can find the volume and the plug it into this equation mass= (density)*(volume) If you have the means you can just submerge the body completely in water and find the volume of the water displaced that will be the mass as waters density is 1 g/cm^3
Area: length multiplied by the width of an object Volume: Has something to do with heigh and base.. Forgot the formula, sorry.
