Answer:
60m^3
Explanation:
In order to find the volume of this shape, you must solve the volume of the 2 different portions separately. You can do this by considering both of them to be rectangular prisms.
The smaller portion has a length of 1, a height of 2, and a depth(? im not sure if its called depth) of 3, you can get the 3 from the depth(?) of the larger one.
Since the volume of a rectangular prism is length x width x depth(?), the smaller figure has an volume of 6 m cubed, or 6m^3
The larger figure has a length of 6, a height of 3, and a depth(?) of 3, meaning you can multiply 3 x 3 x 6, which gives 54, which means the larger figure's volume is 54m^3
Now, you add the volumes of both figures, which gives a volume of 60m^3.
