Answer:
3.75 cubic inches
Step-by-step explanation:
Volume = length x breadth x height
since the box holds 2 layers of 15 cubes
length contains 5 cubes= 5x1/2 inches=2.5 inches
breadth contains 3 cubes=3x1/2inches=1.5 inches
height contains 2 cubes=2x1/2inches=1.0 inches
Volume=2.5x1.5x1.0=3.75 cubic inches
