Cut a part of a rectangular stone with a square bottom, a side length of 3DM and a height of 5DM, and process it into the largest cube as far as possible. Then, what is the volume of the stone chiseled?

3 × 3 × 5 - 3 × 3 × 3, = 45 - 27, = 18 (cubic decimeter); answer: the volume of stone is 18 cubic decimeter

The volume of a cuboid is 320dn cubic. The bottom of the cuboid is a square with a side length of 8cm. What is the height of the cuboid?

320000÷(8×8)=5000cm

A cuboid with a square bottom is just a square with a side length of 4 decimeters after its side is unfolded. What's the volume of this rectangle

Height = bottom circumference = 4, side length = 4 decimeters
Side length = 4 / 4 = 1 decimeter
The volume of this rectangle is 1 × 1 × 4 = 4 cubic decimeters
