Simultaneous reading of mathematical problems The edge of the square glass goldfish jar with water is 5 decimeters long. After putting the goldfish, the water rises 0. What's the volume of the goldfish?
The bottom area of the fish tank is 5 × 5 = 25 square decimeters
The volume of boiled water discharged by goldfish is sh = 25 × 0.5 = 12.5 cubic decimeter
That is, the volume of goldfish is 12.5 cubic decimeters
