Answer:

Volume of a Rectangluar Prism: 288 ft

Volume of triangular prism: 12 ft

Volume of composite figure: 300 ft cubed (^3)

Step-by-step explanation:

Volume of a Rectangluar Prism: V=lwh

[tex]4 \times 6 \times 12 = 288[/tex]

Volume of triangular prism: For this instance, we'll use V=1/2bh

[tex] \frac{4 \times 6}{2} = 12[/tex]

The volume of the composite figure is the total of the volumes added

[tex]288 + 12 = 300ft ^{3} [/tex]
