The volume of a cube is 1 cubic decimeter. What is its edge length? The area of each side? Put a small cube block with edge length of 1 cm into a square with edge length of 1 decimeter We need to arrange these small cubes into a row of decimeter formulas

The volume of a cube is 1 cubic decimeter. What is its edge length? The area of each side? Put a small cube block with edge length of 1 cm into a square with edge length of 1 decimeter We need to arrange these small cubes into a row of decimeter formulas

The volume of a cube is 1 cubic decimeter, and its edge length is 1 (1 * 1) = 1 decimeter
The area of each surface is 1 * 1 = 1 square decimeter
Using a small cube wood block with an edge length of 1cm to make a cube with an edge length of 1dm, you need 1000 pieces (0.1 * 0.1 * 0.1) = 1
Put these cubes in a row, the president = 1 △ (* 0.1 * 0.1) = 100 decimeters
You can understand, agree

Use 2 cm thick wooden board to make a 100 cm long, 65 cm wide and 85 cm high uncovered wooden box, and calculate the volume of the wooden box (accurate to cubic decimeter)

100-2-2 = 96 cm (inside length)
65-2-2 = 61 cm (inside width)
85-2 = 83 cm (inside height)
96 * 61 * 83 = 486048 cubic centimeter = 486 cubic decimeter (volume)

For a rectangular wooden box, the total edge length is 72 decimeters, and the ratio of length, width and height is 3:2:1. What is the volume of the box?

72÷4=18
18÷﹙3＋2＋1﹚=3
Length 3 × 3 = 9
Width 3 × 2 = 6
High 3
The volume of this wooden box is 9 × 6 × 3 = 162 decimeters;
