Answer:
240 cm^3
Step-by-step explanation:
The solid is composed by two rectangular parallelepipeds. To find the total volume we have to find the volume of the two solids and added up.
To find the volume of a parallelepiped we have to use this formula:
V = base surface x height
The area of rectangle is : base x width
So:
Area first rectangle: 4 x 6 = 24 cm^2
V = 24 x 7 = 168 cm^3
Area second rectangle: 4 x 2 = 8 cm^2
V = 8 x 9 = 72 cm^3
total volume = 168 + 72 = 240 cm^3
