What is the volume of this container?

Given:
Container in the shape of two rectangular prism.
To find:
The volume of the container.
Solution:
The clear image of the container is attached below.
Larger rectangular prism:
Volume = length × width × height
= 8 × 5 × 10
= 400
Volume of larger rectangular prism = 400 in³
Smaller rectangular prism:
Volume = length × width × height
= 4 × 4 × 5
= 80
Volume of smaller rectangular prism = 80 in³
Volume of container = Volume of larger prism + Volume of smaller prism
= 400 in³ + 80 in³
= 480 in³
The volume of the container is 480 in³.
