How are cube and sphere alike?

is that cube is (geometry) a regular polyhedron having six identical square faces while sphere is (geometry) the set of all points in three-dimensional euclidean space (or n -dimensional space, in topology) that are a fixed distance from a fixed point.

Which will solidify faster cube or sphere?

The reason for this is that the volume of a sphere is proportional to the cube of its diameter and the surface area is proportional to the square of its diameter. Similarly, it can be shown that molten metal is a cube-shaped mold will solidify faster than in a spherical mold of the same volume.

How are a cube and a cone the same?

A cube has no circular cross-sections but six square faces (necessarily, three mutually perpendicular pairs of parallel faces). Alternatively, on a uniform featureless plane: A cone will roll in circles around one point.

What is the difference between the sphere and the cylinder?

These figures have curved surfaces, not flat faces. A cylinder is similar to a prism, but its two bases are circles, not polygons. The sphere is a space figure having all its points an equal distance from the center point.

What is N in Chvorinov’s rule?

Chvorinov’s rule, which states that ts, the total solidification time, can be computed by: ts = B (V/A) n. where n = 1.5 to 2.0. The total solidification time is the time from pouring to the completion of solidification; V is the volume of the.

What is the difference between cone and sphere?

A cone has one circular base and a vertex that is not on the base. The sphere is a space figure having all its points an equal distance from the center point.

How are a cone and sphere alike?

A right cone is a cone with its vertex directly above the center of its base. has a circular base that is joined to a single point (called the vertex). A sphere is a three-dimensional solid consisting of all points that have the same distance from a given center….Surface Area of a Cone.

Which of the following is not a type of molding sand?

2. Which of the following is not a type of moulding sand? Explanation: Red sand is not counted among the moulding sands, whereas natural sand, synthetic sand and loam sand are various other types of moulding sand, which can be effectively used for casting processes.

Which of the following is a casting process?

Explanation: A casting process in which the molten metal is poured and allowed to solidify while the mold is revolving, is called centrifugal process. The casting produced under this centrifugal force is called centrifugal casting. This process is especially designed for a casting of symmetrical shape.

What is the difference between a sphere and a cube?

A sphere and a cube having equal surface area are made of the same material. A sphere and a cube having equal surface area are made of the same material. The two are heated to the same temperature and kept in identical surrounding. The ratio of their initial rates of cooling is

What is the buoyant force of a cube and a sphere?

The sphere and the cube have same surface area. The buoyant force is A solid cube and a solid sphere both made of same material are completely submerged in water but to different depths. The sphere and the cube have same surface area. The buoyant force is

What is the initial rate of cooling for a cube and sphere?

A sphere and a cube having equal surface area are made of the same material. The two are heated to the same temperature and kept in identical surrounding. The ratio of their initial rates of cooling is (a) 1 : 1

What is the density of a cube of wood in grams?

3g/cm. This means that every centimeter cube of this wood will have a mass of 0.8 grams. Activity 1: (Determine the density of an object with a regular shape.) Obtain a set of objects (cube, cylinder, sphere, etc.) made of the same material. Calculate the density by measuring the mass and volume of your samples.
