Final answer:
The volume of one triangular prism is 45 cm³.
Step-by-step explanation:
To find the volume of the triangular prism, we need to multiply the area of the base by the height. The base of the prism is a triangle, so we can find its area using the formula for the area of a triangle: A = 1/2 * base * height. Plugging in the values, we get A = 1/2 * 4 cm * 4.5 cm = 9 cm².
Now, we can calculate the volume of the prism by multiplying the area of the base by the height: V = A * height = 9 cm² * 5 cm = 45 cm³.
Therefore, the volume of one prism is 45 cm³.
