If it is a cube (basically a square) or a rectangular prism multiply the top, the length, and the base.
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.
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
To find the density of a rectangular solid object, you would calculate the mass of the object by multiplying its volume by its density. For an irregular solid object, you would typically measure its mass using a balance and its volume using displacement of water, then divide the mass by the volume to find the density. The main difference lies in how you determine the volume of the object, with rectangular solids having a straightforward formula for volume calculation compared to irregular shapes which require more complex methods.
Multiply base area x height.
a square is a 2 dimension object. we can not find volume of a 2-D object... if u are asking that of a cube with equal sides, then simply find (a^3) where a is side of the cube.
