The volume of the cuboid is 245 cm³. Each cuboid edge length can be expressed by an integer greater than 1 cm. What is the surface area of the cuboid? - Meadow
On the meadow, there are horses, cows, and sheep grazing together with less than 200. If cows were 45 times more, horses 60 times more, and sheep 35 times more than there are now, their numbers would equal. How many horses, cows, and sheep are in the mead - Bicycle wheels
The driving wheel of a bicycle has 54 teeth. The driven wheel has 22 teeth. How many revolutions will meet the same teeth after? - Amazing number
An amazing number is a name for such an even number, the decomposition product of prime numbers has exactly three, not necessarily different factors, and the sum of all its divisors is equal to twice that number. Find all the amazing numbers. - Shepherd
A shepherd has fewer than 500 sheep. When lined up in rows of 2, 3, 4, 5, or 6, there is always one remaining. However, they can be lined up in rows of 7 with none left over. How many sheep does the shepherd have? - Paper squares

Intervals: 1st bus 40 min. 2nd bus 2 h 3rd bud 20 min How long will it take them to meet - as soon as possible? - Sheep
Shepherd is tending the sheep. Tourists asked him how much they had. The shepherd said, "there are fewer than 500. If I lined up in 4-row, three remain. If in 5-row, four remain. If in 6-row, five remain. But I can form 7-row." How many sheep have a sheph - Biketrial
Kamil was a bike trail. Before hill, he set the forward gear with 42 teeth and the back with 35 teeth. After how many exercises (rotation) of the front wheel do both wheels reach the same position? - Trams 2
The square passes two tram lines. One runs every nine minutes, and the second interval is 15 minutes. Two tram lines arrived in the square exactly at noon. How soon should a similar situation arise again? - Tissues
The store got three kinds of tissues - 132 children, 156 women, and 204 men. Tissues for each species were packed into boxes after the number of pieces was the same for all three types (and greatest). Determine the number if you know that every box has mo - Apples 2
How many minimum apples are in the cart? Is it completely divided into packages of 6, 14, and 21 apples? - Theorem prove
We want to prove the following statement: If a natural number n is divisible by six, then n is divisible by three. What assumption do we start from? - 3 buses
Morning at 5:00 am, three buses started from one place. The first travel in five-minute intervals, the second at 10-minute intervals, and the third at 25-minute intervals. At what hour will the three buses again come from the same place? - Daughters
The man conducting the census asks a woman the age of her three daughters. The woman says when multiplying the age, get the number 72; if their ages add up, get a number of our house, as you see. The man says: That is not enough to calculate their ages. S - Buses
