0.4 × 0.4 × 2 = 0.32 cubic meters or 320 cubic decimeters

A cuboid of wood, the volume is 216 cubic decimeters, cut it into two sections, the surface area increased by 24 square decimeters, the length of this wood () decimeters

After cutting into two sections, two bottom areas are added
Bottom area 24 △ 2 = 12 square decimeters
Length 216 △ 12 = 18 DM
The wood is (18) decimeters long

A wood with uniform thickness is 6 meters long and 216 cubic decimeters in volume. How many square decimeters is its cross-sectional area?

Volume △ length (height) = bottom area, so 216 △ 60 = 3.6 square decimeters
