3. Talk about the results of the observation. Think about it, what does it mean?
What are the commonly used units of area? Guess what are the commonly used units of volume?
Commonly used area units are: square centimeters square decimeters square meters
Commonly used units of volume are: cubic centimeter cubic decimeter cubic meter
How big is 1 cubic centimeter?
A cube with an edge length of 1 cm has a volume of 1 cubic centimeter.
Which objects in life have a volume of approximately 1 cubic centimeter?
3. Independent practice
1. The figures below are all made of small cubes with an edge length of 1 cm. Let’s talk about how many cubic centimeters their volumes are.
2. Choose an appropriate unit name.
The volume of a microwave oven is approximately 40( ).
The area of the textbook cover is approximately 4.4 ( ).
The volume of the container is approximately 40 ( ).
The volume of the pencil case is approximately 200 ( ).
3. Put a cube (edge length 5 cm) gift box into a box (length 40 cm, width 30 cm, height 10 cm). How many boxes can be placed at most? (Material thickness is ignored)
Packed along the "length" of the box, the number of items that can be loaded in a row: 40÷5=8 (pieces)
Packed along the "width" of the box, the number of rows that can be loaded: 30÷5=6 (rows)
Along the "height" of the box, the number of layers that can be installed: 10÷5=2 (layers)
Maximum number of boxes that can be loaded: 8×6×2=96 (boxes)
Answer: It can hold up to 96 boxes.
