Answer:
C.
Step-by-step explanation:
We have been given a container and we are asked to find the volume of our given container.
We can see that our container is made of two cuboids, so we will use volume of cuboid formula to solve our given problem.

We can from provided image that the base cuboid (bigger) has lengths 25 cm, 40 cm and 40 cm.
The height of smaller cuboid will be 25 cm (50 cm -25 cm). The other two sides of smaller cuboid are 35 cm and 40 cm.

Upon substituting our given values in volume formula we will get,

Therefore, the volume of our given container is
and option C is the correct choice.
