If a cuboid, a cylinder and a cone have the same base area and volume, then the height of the cone is cylindrical______ The height of a cuboid is the height of a cone______ ．
The height of cone H = 3vs, the height of cylinder H = vs, the height of cuboid H = vs; the height of cone is cylinder: 3vs △ vs = 3, the height of cuboid is cone: vs △ 3vs = 13, so the answer is: 3 times, 13
If the height of the cylinder is 6dm, the height of the cuboid is (), and the height of the cone is ()
The height of the cuboid is 6dm
The height of the cone is
6×3=18dm、
If the height of the cylinder is 6dm, the height of the cuboid is (6dm), and the height of the cone is (18dm)
A cone is 5cm high, a cylinder is 20cm high, and its diameter is 12cm
The cones are on top of the cylinder. They move together~
(1/3)*3.14*(12/2)*(12/2)*5+3.14*(12/2)*(12/2)*20
=188.4+2260.8
=2449.2 cm3
