What shape is likely to need more material for a critical mass a cube or a sphere?
A sphere is likely to need more material for a critical mass compared to a cube. This is because a sphere has a lower surface area-to-volume ratio than a cube, meaning that for a given volume, a sphere encloses more mass within a smaller surface area. Therefore, to achieve critical mass, a sphere can often require less material than a cube of the same volume.
What is the sequence to grow ver2?
cone, cube, paper, cylinder, the hole than the sphere.
How many more vertices than faces has a cube?
A cube has 8 vertices and 6 faces. Therefore a cube has 2 more vertices than faces.
Why is the half cube has more surface area than cube?
because
Why is a ball a sphere and not a cube?
A ball is a sphere rather than a cube because a sphere is the shape with the least surface area for a given volume. This is known as the isoperimetric inequality, which states that among all shapes with the same volume, a sphere has the smallest surface area. This property makes a sphere the most efficient shape for enclosing a given volume, which is why objects like balls, bubbles, and planets tend to form into spheres in nature. In contrast, a cube has more surface area for a given volume compared to a sphere, making it less efficient in terms of minimizing surface area.
What shape is even more compact than a cube?
A sphere.
What shape is likely to need more material for a critical mass a cube or a sphere?
A sphere is likely to need more material for a critical mass compared to a cube.

Therefore, to achieve critical mass, a sphere can often require less material than a cube of the same volume.
What shape has more than one faces?
Most 3D shapes, such as a cube, cuboid etc. have more than one face (with the possible exception of a sphere).
Can the surface to volume ratio of a sphere be the same as a cube?
No. The surface to volume ratio of a sphere is always smaller than that of a cube. This is because the sphere has the smallest surface area compared to its volume, while the cube has the largest surface area compared to its volume.
What is bigger the surface area of a sphere or the surface area of a cube if they have the same volume?
surface area of sphere = 4πR2 volume of sphere = 4/3πR3 surface area of cube = 6s2 volume of cube = s3 since volumes are equal then s3 = 4/3πR3 s = [cube root (4/3π)] R surface area ofcube = 6 (cube root( 4/3π) times R)2 surface area sphere = 4πR2= 12.56 R2 surface area cube = 15.44 R2 So a sphere has less surface area than a cube with the same volume. Where R= radius of the sphere s=length of side of the cube Sorry,calculation above is now corrected - same equations, earlier made math error - cube has more surface area as you can see

Why is the half cube has more surface area than cube?
because
Which is heavier a cube of platinum or a cube of silver?
A cube of platinum of the same size as a cube of silver will weigh more.
Does a large cube have more mass than a small cube?
A large cube may have more mass than a small cube if it is made from a denser material or if it has a greater volume, meaning more matter is packed into the large cube. However, the size alone does not determine the mass.
Which has more atoms small cube or big cube?
The answer depends on what the substance is. A small solid cube will usually have more atoms than a larger cube filled with a gas.
Why is a ball a sphere and not a cube?
