A cuboid paper box, its bottom is a square with side length of 5 decimeters, its side area is 120 square decimeters


The volume of this carton is 150 cubic decimeters



The bottom is a square cuboid, and the side area is 120 square decimeters


Perimeter of bottom surface = 120 △ 5 = 24 decimeters
Side length of bottom surface = 24 △ 4 = 6dm
Volume = 6 × 6 × 5 = 180 cubic decimeter
A: the volume is 180 cubic decimeters



Bottom is a square cuboid, side area is 120 square decimeters, height is 5 decimeters, volume


120/5=24
24/4=6
6*6*5=180
