You can consider the beam to be a rectangular block. In other words, simply multiply length x width x height.
Volume of prism = area of cross section x length.
Its volume is: cross-section area times its length
just not to confuse you, here is the question more clearer: A prism has a cross section that is a regular hexagon The area of the cross section is 10.4m^2. The volume of the prism is 8.84m^2. Calculate the height of the prism.
length = volume/cross-section
Volume of a cylinder = (area of its cross-section) x (its length) If the end is a circle, then the area of the cross-section = (pi) x (half the diameter)2 = (pi) x (radius)2 Then Volume = pi R2 L
The volume is pi*r^2*h where r is the radius of the circular] cross section and h is the height (or length).
You have to multiply the density of aluminum on its volume. For wires the volume will be the cross section multiplied by the wire length.
Volume = Area of cross section x height
Volume = cross-section area*depth Area of a trapezoid = 0.5*(sum of parallel sides)*width
Volume = area of cross-section*length
The cross section volume of a trapezoid is found between 0 and 2.0.
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.
