- Ice floe
What is the volume of an ice floe weighing 326 kg? - Iron cast
What is the weight of cast iron with a volume of 3575 cubic centimeters? The density of the cast iron is 7600 kg/m3 - Ring
The gold and copper alloy rings weigh 14.5 g and have a volume of 1.03 cm³. How much gold and copper does each ring contain? The metal densities are Au 19.3 g/cm³ and Cu 8.94 kg·dm-3 - Freezer
The freezer has the shape of a cuboid with internal dimensions of 12 cm, 10 cm, and 30 cm. A layer of ice 23 mm thick was formed on the freezer's inner walls (and on the opening). How many liters of water will drain if we dispose of the freezer? - Wood cuboid
What is the mass of a wooden cuboid measuring 15 cm × 20 cm × 3 m, if 1 m³ of this wood weighs 800 kg? - Concrete base
What weight will a cube-shaped concrete base with an edge length of 10 m have if one concrete cube weighs 2200 kilograms? - Petrol consumption
The car's average consumption is x = @ x liters of gasoline per 100 kilometers. How much petrol does a car use on a 320-kilometer road? - Float boya
A spherical float with a diameter of 0.5 m marks the location of a fishing boat's anchor. It floats in salt water. Find the depth to which the float sinks if the material it is made of has a density of 8 kg/m³ and salt water has a density of 1,027 kg/m³. - Water containers
One m³ of wood weighs 650 kg, of which 12% is water. How many 10-liter containers do we need for this amount of water? - Speed of sound
The average speed of sound is 330 metres per second. Estimate how long it will take to hear a church bell 1 km away. Calculate the distance from which you would hear the sound after 10 seconds. - Car - road
The car started at 11:40, traveling 54 km/h between A and B, and arrived at 12:20. Find the distance between A and B. - Two trains
Two trains go at each other. First at a speed of 40 km/h and the second at a speed of 60 km/h. At what distance will it be 30 minutes before they will meet? - Speeds on a hike
The hiking trail leading from Velká Bíteš to Veverská Bítýška is approximately 25 and 1/3 km long. From Velká Bíteš the 1st group of hikers set out at 6:00 a.m. in the morning and from Bítýška the second group of hikers at 7:10 a.m. Both groups met at the - Distance between two cities
The car went from A to B in 4 hours. The car was up 15 km/h faster on the way back. The return trip took 48 minutes shorter than the way there. Find the distance of cities A and B. - Time calculation
How many seconds will the car cover a distance of 50 meters at a speed of 100 km/h? - Cork and swimming
If a person weighs 80 kg, how many kilograms of cork must take a swimming belt to float on water? The density of the human body is 1050 kg/m3, and the cork is 300 kg/m³. (Instructions: Let the human body and cork on a mixture with a density of - Nine balls
Imagine you have nine identical-looking balls, one of which is heavier than the others. You have a balance scale. Describe a procedure to find the heavier ball. What is the minimum number of weighings required? - Inclined plane
On the inclined plane with an inclination angle of 30°, we will put the body (fixed point) with mass 9 kg. Determine the acceleration of the body motion on an inclined plane. - two spacecraft
Recently, two spacecraft successfully landed on two small planets labeled α and β. Both ships were equipped with sensitive sensors that measured the basic parameters of the asteroids. The sensors found that the day α took six times longer on planet α than - Air pressure
The meteorological station measured the air pressure of 1060 hPa (hectopascals). In addition to measuring instruments, there is a residential house with a flat roof with dimensions of 10 m and 28 m. What pressure force in MN (meganewtons) from the air on
