Vấn đề 8. Một container có hình khối có kích thước như trong hình. Các thùng có 54 lít nước trong đó. Bình muốn biết một xô đầy chứa bao nhiêu lít nước , do đó, ông đổ cả xô nước vào container và thấy rằng mức độ của nước tại 7 8 là chiều cao của container. Từ đó, ông có thể tính toán bao nhiêu lít nước một xô đầy chứa . Nếu container rỗng , bao nhiêu xô nước phải Bình đổ vào các container để làm cho nó đầy đủ?

To solve this problem, let's break it down step by step.

Step 1: Calculate the volume of the cuboid container.
The volume of a cuboid is given by the formula:
Volume = Length × Width × Height

Given:
Length = 12 meters
Width = 6 meters
Height = 4 meters

Volume = 12 × 6 × 4 = 288 cubic meters

Step 2: Convert the volume to liters.
Since 1 cubic meter = 1000 liters, we have:
Volume = 288 × 1000 = 288,000 liters

Step 3: Determine the volume of water after pouring a full bucket.
The water level after pouring the bucket is at 7/8 the height of the container, which means the volume of water is 7/8 of the volume of the container.

Volume of water = (7/8) × 288,000 liters = 252,000 liters

Step 4: Calculate the volume of water in one bucket.
Since initially, there were 54 liters in the container and after pouring the bucket, there were 252,000 liters, the volume of water in one bucket can be found by subtracting the initial volume from the final volume.

Volume of water in one bucket = 252,000 liters - 54 liters = 251,946 liters

Step 5: Determine how many buckets are needed to fill the container.
To find out how many buckets are needed to fill the container, divide the volume of the container by the volume of water in one bucket.

Number of buckets needed = 288,000 liters / 251,946 liters ≈ 1.144

Since Bình cannot pour a fraction of a bucket, he would need to pour 2 buckets of water to fill the container completely.

Polly the parrot has learnt to say: "Polly wants a cracker". If she repeat the phrase every five minute for two hour and is given a cracker each time she asks for one.

How many cracker will she eat?

Answer:

2 hours = 120 minutes

The number of the crackers that Polly will eat is:

120/5+1=25 (crackers)

So the answer is 25.

Good luck in studying! ◠‿◠

Giải :

Đi được \(\frac{1}{3}\)quãng đường , tức là phải đi 2 phần nữa và 2 phần này là 6km . Ta có sơ đồ :

                   (          6km                )         

'__________'____________________'

(   Đi được )(             Chưa đi          )

You're a biologist on a mission to keep the rare honeybee Apis Trifecta from going extinct. The last 40 bees of the species are in your terrarium. You've already constructed wire frames of the appropriate size and shape. Your frame is made by equalateral hexagons, and it's shape is like an equalateral triangle with 9 hex on each side of your frame.

Now you need to turn them into working beehives by filling every hex with wax. There are 2 ways to fill a given hexes:
1. Place a bee into the cell. On placed, you can't remove it without killing it.

2. If any unfill cell has 3 or more neighboring wax-filled hexes, the bees already in the hive will move in and transform it. Once the bees have transfomed every hex in the hive, you can add an aditional bee and it'll specialies into the queen. The hive, if been well cared for, will eventually produce new bees and continue the species.

    If there are no hexes with 3 or more transform neighbors, the bees will just sit and wait. And once a bee transform a hex, it will never become a queen.

You could put 40 bees in one wire hive, wait till they transform all the hexes, and then create a queen. But then just one collapses will end the species.

Question: At most how many queen bees you can make with 40 bees?
