A composite figure is considered composite when it is a combination of 2 or more simpler shapes. From the given pairs in the choices above, the most likely to be a composite figure is either the 1st or 2nd set. Those are (8)(6)(6) + (8)(6)(4) and (8)(6)(10) + (8)(6)(4).
The expression that represents the volume of the composite figure, in cubic units, is: 3(8)(6)(6) + (8)(6)(4).
What is the Volume of a Rectangular Prism?
Volume of rectangular prism = (l)(w)(h)
What is the Volume of a Rectangular Pyramid?
Volume of rectangular pyramid = 1/3(l)(w)(h)
The volume of the composite figure = volume of rectangular pyramid + volume of rectangular prism
Volume of the composite figure = 1/3(l)(w)(h) + (l)(w)(h) = 1/3(8)(6)(6) + (8)(6)(4)
Therefore, the expression that represents the volume of the composite figure, in cubic units, is: 3(8)(6)(6) + (8)(6)(4).
