Please help me tysm, )I crossed out the incorrect one.)

Answer:
3,200 cubic inches
Step-by-step explanation:
This an be cut into two parts. The blue and purple.
First, the blue can be calculated as V=4x32x10= 1280in^3
the second seems as if it is missing a length. However, since we can see that the blue box sits perfectly on the purple, it is safe to assume that the missing length is 10.
Hence, the volume can be calculated as V=12x16x10= 1920in^3
Then, you add both the volumes together.
1280+1920= 3,200 cubic inches
