help please i will give brainlys

Answer: 190 m³
Step-by-step explanation:
We will calculate the volume of the prisms separately, and then add them together.
V = L * W * H
[1]
V = L * W * H
V = 9 * 2 * 5
V = 90 m³
[2]
V = L * W * H
V = 5 * 5 * 4
V = 100 m³
[Adding together]
100 + 90 = 190 m³
The volume is 190 m³
