The two right sides of a right triangle are 6cm and 8cm respectively, and the length of the hypotenuse is 10cm. If one side is taken as the axis respectively, then the volume of the hypotenuse is taken as the axis to rotate one circle
The sum of the heights of the two cones is 5cm, and the radius of the bottom surface is 4.8cm. Thus, the volume is: 4.8 * 4.8 * Wu * 5 * 1 / 3 = 120.576cm3
