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 - 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? - Board paint calculation
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 - 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? - 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. - Unknown metal
The prism made of unknown metal has dimensions of 3 cm by 3 cm by 5 cm and a weight of 121 g. What metal is it? Write its chemical symbol. - 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? - Gold weight calculation
How many kg weighs 1 m³ of gold? Au gold density is 19.3 kg · dm − 3 - Calculate sphere
Calculate the surface area and mass of a sphere whose volume is 707.54 cm³, made of a material with a density of 7.8 g/cm³. - Hydrostatic pressure
Please calculate according to Pascal's law. Calculate the hydrostatic pressure at a depth of 300 m below sea level if the density of seawater is approximately 1025 kg per m³. At what depth below the surface is the hydrostatic pressure 4.5 MPa? - Brass sphere
Find the weight of a brass ball with an outer radius of 12 cm and a wall thickness of 20 mm if the brass's density is 8.5 g/cm³.
