Answer:
[tex]\large\boxed{V=180\ cm^3}[/tex]
Step-by-step explanation:
We have two rectangular prisms:
8cm × 5cm × 3cm and 2cm × 5cm × 6cm
The formula of a volume of a rectangular prism a × b × c:
[tex]V=abc[/tex]
Substitute:
[tex]V_1=(8)(5)(3)=120\ cm^3\\\\V_2=(2)(5)(6)=60\ cm^3[/tex]
The volume of the composite space figure:
[tex]V=V_1+V_2\\\\V=120+60=180\ cm^3[/tex]
