- Cylinder can
The paint is sold in a cylinder-shaped can with a height of 24.5 cm and a diameter of 15 cm. A full can weighs 5.5 kg, and an empty can weighs 200 grams. How much does 1 liter of paint weigh? - The vase
The vase is a cylinder with a diameter of 1.2 dm. From the upper edge to the water level, it is 20 cm, and the water depth is 35 cm. If it were filled to the brim, how much ml of water would fit in it? - Rainfall
The annual average rainfall in India was 26 461 mm in Cherrapunji in 1981. How many hectoliters of water fell on one square meter? Would you fit this amount of water into a cube of three meters? - Water level
How high is the water in the cylindrical barrel with a diameter of 12 cm if there is a liter of water? Express in cm with an accuracy of 1 decimal place. - Polygon - area coordinates
Find the perimeter and the area of the polygon with the given vertices. T (2,7), U (2,9), V (5,9), W (5,7) - Tank metal calculation
How many square decimetres of sheet metal are needed for a cube-shaped tank, open at the top with an edge of 75 cm? - Aquarium water calculation
The square-shaped aquarium is 65 cm long, 24 cm wide, and 30 cm high. How many liters of water are in an aquarium if the water reaches 5 cm below its upper edge? - Body volume calculation
When the body was immersed in a cylindrical vessel filled with water, the water level in the vessel rose by 28 mm. Calculate the volume of the immersed body if you know that the diameter of the bottom of the container is 8 cm. - Pool water capacity
The pool has dimensions: a length of 50 m, a width of 15 m, and a depth of 2 m. It is filled with water to 1/4 of its depth. How many hectoliters of water are in the pool? How many hectoliters of water can fit in a filled pool? - Box metal
We make a box in the shape of a cube with an edge of 12 cm. How many cm² of sheet metal do we need to create a box if we do not make the lid? - How much
How much money will we pay for 20 planks 4m long, 15cm wide, and 26mm thick when 1m³ of wood costs 4500kč? - Vase capacity
The cylindrical vase is 28 cm high. Its inner diameter d = 1.1 dm. How many liters of water will fit in it if the bottom thickness is 1.5 cm? - Hydrostatics
A) Calculate the pressure (hydrostatic) at the bottom of the Mariana Trench. The density of seawater is 1,030 kg/m³. What do you need to find out in an atlas or on the Internet? b) Calculate the pressure force acting on a submarine with a volume of 2,000 - Ball collision speed
Two inelastic/plastic balls move towards each other with equal velocities of 2 m/s. The weight of one ball is 3kg, the other 1kg. Determine the speed of the balls after the collision and the loss of kinetic energy. - The temperature 29
The temperature at 6 P.M. is -11°Fahrenheit. During the night, the temperature rises by 7°F drops by 3°F, and rise by 5°F. What is the temperature after these changes? - Central Park
Central Park is a rectangular park in New York City, and the map scale is 1 cm: 320 m (It means 1 cm on the map represents 320 m in the real world. ). Find the north-south distance if the length on the map is 2.5 cm. - Summerjob
Temporary workers Franta ties a sheaf of hay in 20 minutes, Lojza only a quarter in the same time. How many sheaves do they tie together in 8 hours? - Cycling
The cyclist goes on a trip. First, I drove at 3 hour at an average speed of 44 kilometers per hour, then slowed down, and another 2 hours driving at a speed 21 kilometers per hour. How many total kilometers are cycling? - A chemist
A chemist recorded the change in temperature of a cooling liquid as −25.5° over a 1.5-minute period. The temperature fell at a constant rate. What was the rate of change in temperature? Enter your answer in the box. °F per minute - Truck kinetic energy
The truck travels at a constant speed of 70 km/h. The first time it goes empty, and the second time it comes with a load. In which case is its kinetic energy smaller?
