The shape in the image is a trapezoidal prism. To find the volume of a trapezoidal prism, we can use the formula:

$\text{Volume} = \text{Area of trapezoidal base} \times \text{Height (depth of prism)}$

Step 1: Find the Area of the Trapezoidal Base

The area $A$ of a trapezoid can be calculated using the formula: $A = \frac{1}{2} \times (a + b) \times h$ where:

• $a$ and $b$ are the lengths of the parallel sides (10 cm and 6 cm in this case),
• $h$ is the height (5 cm).

Substitute the values: $A = \frac{1}{2} \times (10 + 6) \times 5 = \frac{1}{2} \times 16 \times 5 = 40 \, \text{cm}^2$

Step 2: Multiply by the Height (Depth) of the Prism

The depth of the prism is given as 15 cm. Therefore, the volume $V$ is: $V = 40 \times 15 = 600 \, \text{cm}^3$

Final Answer

The volume of the trapezoidal prism is: $\text{Volume} = 600 \, \text{cm}^3$
