Answer:
20 cubic meters
Step-by-step explanation:
Volume of a rectangular prism = length * width * height
Dividing the figure into 2 rectangular prisms
Volume of First rectangular prisms = 4m * 2m * 1m
Volume of First rectangular prism = 8m^3
Volume of second rectangular prism = 4m * 3m * 1m
Volume of second rectangular prism = 12m^3
Taking the sum
Volume of the figure = 8m^3 + 12m^3
Volume of the figure = 20 cubic meters
