Multiply area of the base by height of the figure.
Area=Bh when B=area of the base, and h=height of the prism/cylinder
Both the cylinder and rectangular prism are solid objects. Volume of both can be found by multiplying the area of the base by the height.
Volume of a prism and a cylinder= cross-section area*height or length
Volume of a Rectangular Prism The volume of a rectangular prism can be found by the formula: volume=length*width*height
A cylinder is not a prism because it has a circular base and therefore requires a different formula to figure out its volume, surface area, etc.
Formula for the volume of both a Prism and a Cylinder is V = Bh (where B = area of the base, and h = height)
The volume of the pyramid and cone is one third the volume of the corresponding (ie same [size] base and height) prism and cylinder.
Volume of a cylinder is easy: Vol= [(pi) x radius^2] x height of cylinder] Where Pi= 3.1416 approx and radius = 1/2 of cylinder diameter The volume of a prism is complicated because it depends on the type of prism. for a regular shape prism the formula is : Vol = (area of base) x height If the prism is a "union" of differents shapes, you have to split the prism in smaller/single/easy shapes and calculate the volumes individually and then add the resulting volumes
A cylinder.
The volume of a rectangular prism can be found by the formula: volume=length*width*height
To find the base area of any prism, including the circular prism called cylinder, divide the volume by the height.
To find the volume of a prism you first need to know the area of cross section. Then, Volume of prism = area of cross section x length.
