- Hydrostatics
A) Calculate the hydrostatic pressure at the bottom of the Mariana Trench. The density of seawater is 1,030 kg/m³. What depth do you need to look up in an atlas or on the Internet? B) Calculate the pressure force acting on a submarine with a surface area - Six-tonne truck
The platform of a six-tonne truck is 2.20 m wide and 4.20 m long; the side panels are 0.75 m high. How many cubic metres of gravel could be loaded onto the truck with the load levelled to the top of the side panels? How deep a layer of gravel can be loade - Jelly sugar ratio
Did Sonia not like the ratio indicated on the jelly sugar; which picture is wrong and why? A) for 1000 g of fruit, add 350 g of sugar 3:1: super jelly sugar B) 3:1 for 1500 g of fruit, add 500 g of sugar: extra jelly sugar - Ice volume calculation
What is the volume of 320 kg of ice floes in liters? - Concrete column
A concrete column for a motorway bridge is a cuboid with dimensions 1 m × 0.8 m × 25 m. A crane must lift it to a height of 20 m. What is the minimum power of the crane's engine if the lift takes 2 minutes? - Wafer filling weight

Štěpán painted a block-shaped steel board measuring 2.2 m, 1.5 m, and 1.6 m twice with a protective coating. How many kilograms of paint would he consume if he used 120 g of paint per 1 m²? - Convex lens
The convex lens consists of two spherical segments (dimensions given in mm). Calculate its weight if the density of the glass is 2.5 g/cm³. Dimensions: 60 mm in length and width of the upper part 5 mm, the width of the lower part 8 mm - Tank painting calculation
We painted a closed cube-shaped oil tank with an edge length of 1.5 meters twice with a protective coating. How many kilograms of paint did we use if 1 kg of paint is enough for 10 square meters? How many liters of oil are in the tank if it is filled to t - Coke and coal
20.1 tons of coke is produced from 30 tons of black coal. How much coke is made from 1 kilogram of coal? - Barrel paint calculation
How many kg of paint do you need to buy to paint a 1.5 m high cylinder-shaped rainwater cover with a 0.7 m radius? We paint the barrel from the outside and inside, and 100 grams of paint is needed to paint 1 square meter. - The body
The body has 2 m, 2 dm, and 10 cm dimensions. It weighs 28 kg. What is the density? - Diver
Please calculate using Pascal's law. The window of the diving helmet has a surface area of about 7 dm². What pressure force acts on the window at a depth of 20 meters below the water surface? - Barrel painting calculation
The water barrel, 90 cm high and 60 cm wide, has no lid (upper base). How much paint do we need to paint the barrel from the outside? If 1 kg of paint is enough for 8 m². - Sugar density calculation Determine the density of sugar if 0.25 cubic meters in the container weighs 0.403 tons
- Pillar cement calculation
How many tons of cement are needed to concrete two pillars 6.5 m high with a base in the shape of four squares joined into one cross of dimensions 1.2 m? 2.5 q of cement is needed for 1 cubic meter of concrete. - Brick wall
What is the weight of a solid brick wall that is 30 cm wide, 4 m long, and 2 m high? The density of the brick is 1500 kg per cubic meter. - Dead Sea water
When Vera visited the Dead Sea, she took a bowl with sand, pebbles, and water from the sea as a souvenir. The water in the bowl weighed 400 g. How many deciliters of water did she carry away from the sea? The density of salt water in the Dead Sea is 1.240 - The body
The body has a volume of 15 cubic centimeters and a weight of 117 grams. What is the density? - Chained winch
When digging a well, a chained winch balances the material. An empty shackle weighs 8 kg, a total of 64 kg. What force must the worker exert on the crank handle when pulling the shackle with a constant movement from a depth of 5 m if the shaft diameter is
