Cube is inscribed into the sphere of radius 181 dm. How many percent is the volume of cube of the volume of the sphere?
• Inscribed sphere
How many % of the volume of the cube whose edge is 6 meters long is a volume of a sphere inscribed in that cube?
• Reduce of the volume
Calculate how many % reduce the volume of the cube is we reduced length of each edge by 10%.
• Sphere fall
How many percent fall volume of a sphere if diameter decrease 3×?
• Inscribed sphere
How many percent of the cube volume takes the sphere inscribed into it?
• Volume and body diagonal
Calculate how much the volume and body diagonal of the cuboid decrease if we reduce each of its three edges a, b, c by 18%?
• Mixture
How many percentages mixtures do we get by adding 23ml of matter to 89ml of water?
• Cube edges
If the edge length of the cube increases by 50%, how does the volume of this cube increase?
• Water tanks
A different amount of water is poured into each of the three identical vessels. In the first vessel, water fills 30% of its volume and in the second vessel 40% of its volume. The third container contains 19 liters of water. If we distributed the water fro
• Barrel
The barrel is filled with water up to 57% of its capacity. When we add two buckets will be filled to 73% of its capacity. What is the volume of a barrel, if the volume of the bucket is 12 liters?
• Cone in cylinder
The cylinder is inscribed cone. Determine the ratio of the volume of cone and cylinder. The ratio express as a decimal number and as percentage.
• Cone in cube
The cube is inscribed cone. Determine the ratio of the volume of cone and cube. The ratio express as a decimal number and as percentage.
• Lathe
Calculate the percentage of waste if the cube with 53 cm long edge is lathed to cylinder with a maximum volume.
• Cuboid enlargement
By how many percent increases the volume of cuboid if its every dimension increases by 30%?
The radius of the sphere we reduce by 1/3 of the original radius. How much percent does the volume and surface of the sphere change?
• Volume increase
How many percent will increase in the pool 50 m, width 15m if the level rises from 1m to 150cm?
• Beer tapping
When checking compliance with the beer tapping, it was found that 60% of the offered beers were underfilled. The others were fine. Thus, instead of 0.5 l, the volume was 4.4 dcl on average. What was the volume of one average underfilled beer?
