The height of a cylinder is 5 decimeters, the side area is 62.8 square decimeters, and the volume is 1______ .

The height of a cylinder is 5 decimeters, the side area is 62.8 square decimeters, and the volume is 1______ .

(62.8 △ 5) △ 3.14 × 2, = 12.56 △ 6.28, = 2 (decimeter); 3.14 × 22 × 5, = 3.14 × 4 × 5, = 62.8 (cubic decimeter); answer: its volume is 62.8 cubic decimeter. So the answer is: 62.8 cubic decimeter
