Please help. Please refer to the picture I really need to finish this.

Answer:
20cm^3
Step-by-step explanation:
The figure is composed by two parallelepipeds
first one
base area = 2 x 1 = 2 cm^2
height = 3 + 2 = 5 cm
V = base area x height
V = 2 x 5 = 10cm^3
second one
base area = 2 x 1 = 2 cm^2
height = 7-2 = 5 cm
V = 2 x 5 = 10 cm^3
total volume = 10 x 2 = 20 cm^3
