What is the volume of the rectangular prism?
A) 2.1 in3
B) 5.25 in3
C) 21 in3
D) 42 in3

The volume of the rectangular prism would be 5.25 cubic inches. The correct answer would be an option (B).
The volume of the rectangular prism is the product of the base area and the height.
Given the height of the prism is 1.5 inches, the length of the prism is 1 inch and the length of the prism is 3.5 inches.
The volume of the rectangular prism would be :
⇒ Base Area × Height
⇒ Length × Width × Height
⇒ 3.5 in × 1 in × 1.5 in
Apply the multiplication operation, and we get
⇒ 5.25 in³
Hence, the volume of the rectangular prism would be 5.25 cubic inches.
