The radius and height of the bottom of a cone are equal to the length of a cube. The volume of the cube is 216 cubic decimeters. What is the volume of the cone
The volume of the cube is 216
So, its side length is 6 decimeters, (6 × 6 × 6 = 216)
1/3×3.14×6²×6
=3.14×36×2
=226.08 (cubic decimeter)
The volume of a cube is 1 cubic decimeter, its Ling length is (), and the area of each side is ()
1 decimeter
Use a small square with a length of 2 cm to form a large cube. The volume of the large cube is () cubic decimeter
Use a small square with a length of 2 cm to form a large cube. The volume of the large cube is (64) cubic decimeters
2 × 2 × 2 × 8 = 64 cubic decimeter
The length of a cube is 5 decimeters. If you reduce its length by 1 decimeter, how many square decimeters will its surface area be reduced, and how many cubic centimeters will its volume be reduced
The original volume is 125 and the surface area is 150
After 1 reduction, the volume is 64 and the surface area is 96
Volume reduction 125-64 = 61 surface area reduction 150-96 = 54
The surface area of this cuboid is______ Square decimeter, volume is______ Cubic decimeter
Surface area: 1 × 1 × 10 = 10 (square decimeter), volume: 1 × 1 × 2 = 2 (cubic decimeter); answer: the surface area of this cuboid is 10 square centimeter, volume is 2 cubic centimeter
As shown in the figure, it is made up of a cube with an edge length of 5cm. How many cubic centimeters is its volume? What is its surface area in square centimeters?
(1) 5 × 5 × 5 × 9, = 125 × 9, = 1125 (cubic centimeter); (2) 5 × 5 × 4 × 2 + 5 × 5 × 5 × 2 + 5 × 5 × 7 × 2, = 200 + 250 + 350, = 800 (square centimeter); a: the volume of the figure is 1125 cubic centimeter, and the surface area is 800 square centimeter
The circumference of a rectangle is 18 cm, and its length and width are in whole centimeters. What is the area of the rectangle?
If 18 / 2 = 9, the sum of length and width of a rectangle is 9 cm. It can be divided into the following situations: 1. Length 8 cm, width 1 cm, area 8 square cm; 2. Length 7 cm, width 2 cm, area 14 square cm; 3. Length 6 cm, width 3 cm, area 18 square cm; 4. Length 5 cm, width 4 cm, area 20 square cm
