Identify the volume of the composite figure. Round to the nearest tenth. Help please

Answer:
224 m^3.
Step-by-step explanation:
We could do this by calculating the product of the length width and height of the whole solid then subtracting the volume of the cube that is ' cut out' of it, that is :
12 * 6 * 4 - 4*4*4
= 288 - 64
= 224 m^3.
