Description

"Volume of a cuboid" Cuboid (2) PPT

Part One: Learning Objectives

1. Further master the calculation method of the volume of cuboid and cube. (emphasis)

2. Be able to use the volume formulas of cuboids and cubes to solve some simple practical problems. (difficulty)

Volume of cuboid PPT, part 2: exploring new knowledge

Knowledge points General formulas for the volume of cuboids and cubes

(1) First calculate the volumes of the following figures, then read them and think about them. (Unit: dm)

The area of ​​the shaded part is the area of ​​the base of each figure above, which is called the base area.

Volume of cuboid (cube) = base area × height

V＝S×h＝Sh

Knowledge refining

The volume of a cuboid (or cube) = base area × height. Use V to represent the volume of the cuboid (or cube), and use S and h to represent the base area and height of the cuboid (or cube) respectively. Then V = Sh.

Knowledge points Application of general formulas for cuboids and cubes

(2) Fill it out.

Knowledge refining

According to the volume of the cuboid (or cube) = base area × height, we can get the base area = the volume of the cuboid (or cube) ÷ height, and the height = the volume of the cuboid (or cube) ÷ base area.

Volume of cuboid PPT, Part 3: Consolidation exercises

1. A rectangular pool has a bottom length of 12dm and a width of 6dm. If we want to inject 2dm of water into this pool, how many liters of water will be needed? (Selected from textbook P43 T5)

12×6×2＝144（dm³）＝144（liter）

Answer: 144 liters of water are required.

2. The toothpaste box is 15cm long, 3cm wide and 3cm high. There is a carton, the dimensions of the inside are as shown in the figure (unit: cm). How many boxes of toothpaste can be placed in this carton? Talk to your peers and tell them what you think. (Selected from textbook P43 T6)

60÷15＝4

30÷3＝10

4×10×10=400 (box)

Answer: This carton can hold up to 400 boxes of toothpaste.
