- Granite block volume
The granite block weighs 8.7 tons. The density of granite is 2.9 g / cm³. Find the volume of the block in m³. - Nutballs
The dough for nutballs contains, among other things, two basic raw materials: flour and nuts, in a ratio of 2:1. How much flour is needed, and how many nuts are needed for 1 kg of dough if the "other" is 100 g? - Kerosene in the bottle
The volume of kerosene in the bottle is 10 cm³. Find the weight of the fluid. (its density is ρ = 830 kg/m³) - Wall thickness
The hollow metal ball has an outside diameter of 40 cm. Determine the wall thickness if the weight is 25 kg and the metal density is 8.45 g/cm³. - Wood density calculation
Calculate the density of 2.5 tons of wood, knowing it takes up three cubic meters. Express the result in g / dm cubic. - Truck load capacity The load capacity of the truck is 10t. Will it carry 200 oak planks measuring 30 cm, 4 m, and 30 mm at a time if the weight of 1 dm³ of oak wood is 0.7 kg?
- Ball shot calculation
How many ball shots with diameters of 2 mm can be made of 1 kg of special metal alloy with a density of r = 7550 kg/m³? - Roof paint consumption
The cone-shaped sheet metal roof has a base diameter of 80 cm and a height of 60 cm. If 1 kg of paint is consumed per 6 m² of sheet metal, calculate the paint consumption for painting this roof. - Strawberry sugar ratio
An old cookbook states that 250g of gelling sugar should be added to 1.25kg of strawberries when preparing strawberry jam. What is the sugar-to-strawberry ratio? - Aquarium
Try to estimate the weight of the water in an aquarium 50cm long and 30cm wide when poured to a height of 25cm. Find the weight of the aquarium's water. - Nitrogen
One bag of urea containing 46 percent nitrogen weighs 25 kg. How many bags must be purchased for fertilizing a field of 41003 square meters if the nitrogen dose is 50.0 kg per hectare? - The bridge
A vehicle weighing 5,800 kg passes 41 km/h on an arched bridge with a radius of curvature of 62 m. What force pushes the car onto the bridge as it passes through the center? What maximum speed can it cross over the bridge's center so it does not fly off t - Angled cyclist turn
The cyclist passes through a curve with a radius of 20 m at 25 km/h. How much angle does it have to bend from the vertical inward to the turn? - Rotaty motion
What minimum speed and frequency do we need to rotate with the water can in a vertical plane along a circle with a radius of 70 cm to prevent water from spilling? - The prison ball
Calculate the density of the material from which the prison ball is made if you know its diameter is 15 cm and its weight is approximately 2.3 kg. With the help of mathematical-physicochemical tables, estimate what material the ball is made from. - Heat capacity
In a clay vessel there is water with a mass of m = 0.80 kg and a temperature of t1 = 15°C. An Indian woman took from a fireplace four basalt stones, each with a mass of m2 = 0.2 kg and with a temperature of t2 = 450°C, and - Grass seed calculation
We should sow grass in a square-shaped garden with a side of 16.2 m. How many kg of grass seed do we need? One square meter is necessary for 25 grams. - A flower pot
The concrete flower pot has the shape of a cube with an edge of 45 cm, and the thickness of the walls and bottom is 4 cm. A) Calculate the clay volume in the flowerpot if it reaches 3cm below the rim. B) Calculate the weight of the flowerpot if the concre - Spruce log weight
Spruce logs with a diameter of 270 mm and a length of 4 m are carefully loaded onto a wagon with a bed width of 2,700 mm and stacked in 9 layers. How much does such a load of spruce wood weigh if its density is 700 kg/m³? - Shopping payment calculation
In the store, Janko bought 300g of ham, 5 rolls, 1.5kg of tomatoes, and 2l of milk. Unit prices are listed in the table - ham 6.50e/kg rolls 0.06e/pc tomatoes 3.4e/kg milk 0.95e/l. How much did Jeniček pay for the purchase?
