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.
Dịch : Alex có 1 bộ sưu tập huy hiệu rất tuyệt mà anh ấy muốn đếm.Anh ấy biết rằng số huy hiệu nằm trong khoảng 120 -> 150 nhưng ko biết chính xác con số.Anh ấy quyết định đếm nhóm 5 và dư ra 2.Sau đó anh ấy đếm nhóm 6 và dư ra 3.Bạn có thể tính chính xác số huy hiệu mà Alex có ko ?
Giải : Gọi số huy hiệu Alex có là a\(\left(120\le a\le150\right)\)thì a : 5 dư 2 ; a : 6 dư 3
=> a + 3 chia hết cho 5 và 6 (vì 5 - 2 = 3 ; 6 - 3 = 3) => (a + 3)\(⋮\)30 => a + 3 = 150 (vì\(123\le a\le153\)) => a = 147
Vậy Alex có 147 huy hiệu
1 . his name nam
2. he is twenty-three years old
3. he is an engineer
4.five people in his family
5. his father is fifty
6. yes,he does
7. his mother is forty-eight years old
8. thiếu đề
Theo đề bài, ta có: Reid viết văn bản trong tháng 11:1
...........................tháng 12: 2
.............................tháng 1: 4
.............................tháng 2: 8.
Đây là dãy số quy luật: 1,2,4,8.... (mỗi số cách nhau x2)
Vậy tháng 3 là 16
Đáp án: 16
