V.5 Which is better?


Find the volume of the composite figure.

Damien's "Rectangle-Triangle" Method
I split the figure into two shapes, a rectangular prism and a triangular prism.
I label each new shape with the lengths from the original diagram.
I use the original dimensions to find the volume of the rectangular prism.
I do the same thing with the triangular prism.
I add the volumes to find the volume of the whole figure!
