A container with a square bottom is filled with water. The side length is 13 cm and the height of water is 6 cm. Put a 15 cm iron solid cone upright in the container and the height of water rises to 10 cm. Then the volume of the cone is 10 cm______ Cubic centimeter


The water part is a small cone, the height is 13 times of the big cone, and the radius is 13 times of the big cone, so the volume is (13) 3 = 127 of the big cone, then the volume of the big cone is: 13 × 13 × (10-6) △ 1-127, = 169 × 4 △ 2627, = 676 × 2726, = 702 (cubic centimeter); answer: the volume of the cone is 702 cubic centimeter, so the answer is: 702
