D. 170 cm^3

Answer 1

Answer:B

Explanation:

Answer 2

`\large\boxed{V=180\ cm^3}`

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:

`V=abc`

Substitute:

`V_1=(8)(5)(3)=120\ cm^3\\\\V_2=(2)(5)(6)=60\ cm^3`

The volume of the composite space figure:

`V=V_1+V_2\\\\V=120+60=180\ cm^3`
