The glass cube dive into the aquarium, which has a length of 25 cm, width 20 cm and height of 30 cm. Aquarium water rises by 2 cm. a) What is the volume of a cube? b) How many centimeters measure its edge? - Volume from surface area

What is the volume of the cube whose surface area is 96 cm^{2}? - Hollow sphere

The steel hollow sphere floats on the water plunged into half its volume. Determine the outer radius of the sphere and wall thickness, if you know that the weight of the sphere is 0.5 kg and the density of steel is 7850 kg/m^{3} - Water level

The glass container has a cuboid shape with dimensions of the bottom 24 cm and 12 cm. The height of the water is 26 cm. Calculate the body's volume, which is sunk into the water if the water level rise by 3 cm. - Cube basics

How long is the edge length of a cube with volume 15 m^{3}? - Cuboid

Find the cuboid that has the same surface area as the volume. - Chemical parison

The blown parison (with shape of a sphere) have a volume 1.5 liters. What is its surface? - Cylinder - area

The diameter of the cylinder is one-third the length of the height of the cylinder. Calculate the surface of cylinder if its volume is 2 m^{3}. - Surface of the cylinder

Calculate the surface area of the cylinder when its volume is 45 l and the perimeter of base is three times of the height. - Iron sphere

Iron sphere has weight 100 kg and density ρ = 7600 kg/m^{3}. Calculate the volume, surface, and diameter of the sphere. - The body

The body on the figure consists of cubes with an edge length 10 cm. What surface has this body? - Three dice

When you throw three dice was the sum total of the dice 10. The yellow dice fell one eye more than on the red and brown fell 3 eyes less than red. How many eyes fell on every dice? - Wood

Wood cube with edge 11 cm weights 0.753 kg. What weight have 10, 100 and 1000 these cubes? - Funnel

The funnel has the shape of an equilateral cone. Calculate the surface wetted with water if we poured into the funnel 7.1 liters of water. - Prism X

The prism with the edges of the lengths x cm, 2x cm, and 3x cm has volume 20250 cm^{3}. What is the area of the surface of the prism? - Center of the cube

The Center of the cube has a distance 16 cm from each vertex. Calculate the volume V and surface area S of the cube. - Balls

Three metal balls with volumes V_{1}=71 cm^{3}V_{2}=78 cm^{3}and V_{3}=64 cm^{3}melted into one ball. Determine it's surface area. - Rotary cone

The volume of the rotation of the cone is 472 cm^{3}, and the angle between the side of the cone and the base angle is 70°. Calculate the lateral surface area of this cone. - Tereza

The cube has an area of base 256 mm^{2}. Calculate the edge length, volume, and area of its surface. - Task

I have homework. The cube has an edge 7 cm long and I must find wall and body diagonal.
