Description

"Calculation of the volume of cuboids and cubes" PPT courseware on the understanding of cuboids and cubes

teaching objectives

1. Be able to derive the volume formulas of cuboids and cubes

2. Remember the volume formulas of cuboids and cubes

3. Be able to apply formulas to correctly calculate the volumes of cuboids and cubes

fill in the blank:

1. ( ) is called the volume of an object.

2. To measure the volume of an object, look at ( ).

Students randomly take out some small squares prepared before class, work in groups, place different cuboids on the table, and fill in the relevant data and your findings into the "Experiment Report Sheet" (as shown below).

(1) Based on the above data, can you find out what is the relationship between the number of small squares contained in a cuboid and its length, width, and height? Number of small squares = ( )

(2) The number of small squares is ( ) of each cuboid

(3) Can you summarize the formula for calculating the volume of a cuboid? The volume of a cuboid =__________.

clever judgment

1. The volume of both cubes and cuboids can be calculated by multiplying the base area by the height. ( )

2. Two cuboids with equal volumes must also have the same shape. ( )

3. The longer the length, width, and height of the cuboid, the larger the volume. ( )

1. The length of a brick is 24 cm, the width is 12 cm, and the thickness is 6 cm. What is its volume in square centimeters?

2. A cube of stone has an edge length of 7 decimeters. What is the volume of this stone in cubic decimeters? If 1 cubic decimeter of stone weighs 2.7 kilograms, how many kilograms does this stone weigh?

Optional question: Can you calculate it differently?

The school transported 7.6 cubic meters of sand and spread it in a sand pit that is 5 meters long and 3.8 meters wide. How thick can it be spread?
