The biggest animal on land is an elephant, and the biggest animal in the sea is a whale. Why are the animals in the sea bigger than those on land? Solve it with mathematics.
You know that. If the height of an animal on land is increased by 10 times, its volume is 1000 times, but its feet are only 100 times, that is, if it is too big, it just can't stand up. In the ocean, water has buoyancy, which counteracts a lot of gravity. Explain. . Looking at a line segment with a 3-fold magnifying glass, the length of the line segment is 3 times, the surface area of a square is 9 times, and the volume of a cube is 27 times, which means that the line segment is 3 times. The surface area is 3.2 times. 3 3 times the volume = = animals such as elephants on land and whales in the sea.
