The surface area of a cuboid is 16000 square decimeters, and the bottom surface is a square with a side length of 40 cm. What is the volume of the cuboid

The surface area of a cuboid is 16000 square decimeters, and the bottom surface is a square with a side length of 40 cm. What is the volume of the cuboid?
40 cm = = 4 decimeters
The height of the cuboid is:
(16000-4*4*2)/(4*4)
==998 (decimeter)
So the height of the cuboid is 998 decimeters
