The volume of a rectangular prism is calculated by multiplying the length, width, and height.
In this case, the prism is made of 3 columns, 2 cubes high, and 2 cubes deep. Therefore, the length is 3 cubes (3 x 1/2 = 1 1/2 inches), the width is 2 cubes (2 x 1/2 = 1 inch), and the height is 2 cubes (2 x 1/2 = 1 inch).
So, the volume = 1 1/2 x 1 x 1 = 3/2 cubic inches
The correct answer is A. 3/2.
