1. The problem asks for the volume in cubic units of the given shapes made of unit cubes. 2. Volume of a prism or solid made of unit cubes is the total number of unit cubes it contains. 3. For the yellow cube prism (top-center), count the cubes: it is a $3 \times 3 \times 3$ cube, so volume = $3 \times 3 \times 3 = 27$ cubic units. 4. For the red cube prism (top-right), count the cubes: it is a $2 \times 3 \times 4$ prism, so volume = $2 \times 3 \times 4 = 24$ cubic units. 5. For the purple L-shaped figure (bottom-center), count the cubes by parts: the vertical part has $2 \times 1 \times 3 = 6$ cubes, the horizontal part has $3 \times 1 \times 1 = 3$ cubes, total volume = $6 + 3 = 9$ cubic units. 6. For the green cube prism (bottom-right), count the cubes: it is a $2 \times 2 \times 2$ cube, so volume = $2 \times 2 \times 2 = 8$ cubic units. Final answers: - Yellow prism volume = 27 cubic units - Red prism volume = 24 cubic units - Purple L-shaped figure volume = 9 cubic units - Green prism volume = 8 cubic units
