Answer: B. 140 cubic inches.
Step-by-step explanation:
The question is asking you to find the volume of the rectangular prism.
You can find this by using this formula:
[tex]V = w*h*l[/tex]
Where w is the width, h is the height, and l is the length.
Substitute the sides of the rectangular prism into the equation:
[tex]V = 3.5 * 10 * 4\\\\V = 140[/tex]
The volume of the prism is 140 cubic inches.
The correct answer is B.
