# Sphere + cube root - problems

- Cube in a sphere

The cube is inscribed in a sphere with volume 3724 cm^{3}. Determine the length of the edges of a 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. - Hollow sphere

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 density of steel is 7850 kg/m^{3} - Plasticine ball

Plasticine balls have radius r_{1}=75 cm, r_{2}=35 cm, r_{3}=91 cm. For these balls are molded one big ball. Calculate the radius r of the resulting ball. - Shots

5500 lead shots with diameter 4 mm is decanted into a ball. What is it diameter? - Iron sphere

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

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

We apologize, but in this category are not a lot of examples.
