To find the volume of a rectangular prism, you multiply the base area by the height of the prism.
First, let's find the area of the triangle base:
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * 8 cm * 3 cm
Area of triangle = 12 cm²
Now, we can find the volume of the rectangular prism:
Volume = base area * height of prism
Volume = 12 cm² * 12 cm
Volume = 144 cm³
Therefore, the volume of the rectangular prism is 144 cm³.
Find the volume of this figure.
