The given shape is a rectangular prism with a triangular prism on top. The dimensions provided are:
Rectangular prism: 5 units (length), 3 units (width), 2 units (height)
Triangular prism: 3 units (base), 3 units (height), 1.5 units (depth)
Step 2: Calculate the Volume of the Rectangular Prism
The volume \( V \) of a rectangular prism is given by:
\[ V = \text{length} \times \text{width} \times \text{height} \]
\[ V = 5 \times 3 \times 2 = 30 \text{ cubic units} \]
Step 3: Calculate the Volume of the Triangular Prism
The volume \( V \) of a triangular prism is given by:
\[ V = \frac{1}{2} \times \text{base} \times \text{height} \times \text{depth} \]
\[ V = \frac{1}{2} \times 3 \times 3 \times 1.5 = \frac{1}{2} \times 13.5 = 6.75 \text{ cubic units} \]
Final Answer
The total volume of the combined shape is the sum of the volumes of the rectangular prism and the triangular prism:
\[ V_{\text{total}} = 30 + 6.75 = 36.75 \text{ cubic units} \]
