2 smaller drawer volume is 3510
3 larger drawer volume is 7371
Total is 10881
Step-by-step explanation:
2 small drawers volume is 2×351×5
Since base area (l×b)is 351 and depth/height is 5 also 2 because there are two drawer 3 larger drawer with base area as 351 and depth/height as 7 so volume is 351×7×3 3because three drawers
