The difference in compressive strength is due to the difference between the modulus of elasticity of concrete and that of the steel which is used to apply the compressive force on the concrete. The pressure applies a lateral confinement pressure which is equal to d/3 meaning that for the cylinder, 2d/3 is confined leaving d/3 unconfined whereas for the cylinder 2d/3 is confined means all of the cube is confined. This leads to the cube having a higher compressive strength that the cylinder. For more information, try to read about the triaxial test and the effect of confinement on the compressive strength of soil samples.
A cube is a special kind of prism.
A square is 2D and a cube is 3D.
It's the same as the difference between a factor and a multiple. 3 x 3 x 3 = 27 27 is the cube of 3. 3 is the cube root of 27.
Well a square cube is the same length on all sides unlike a rectangle cube.
Cylindrical strength = 85% of Cube strength.
There is not much difference between a cube and a cylinder. The cube is a 3d square and a cylinder is actually 3d circle in a rectangle form.
a cube is a 3d square and a cylinder is 3d circle + rectangle shape.

With regards to concrete strength, a cylinder test strength is usually between 5 and 25 percent less than a cube test strength. You can also try using this equation: fbk=(fck-1.77)/0.83 where fbk is cubic concrete strength and fck is cylindrical strength.
cylinder
The equivalent concrete for M-30 cylinder strength is M-40 cube strength
Because I say so.
Reasons for concrete cube to have greater compressive strength as compared to cylinder iscontact area of a standard cube mould with the upper platen in the testing machine is more which results in more confinement .more confinement resist against specimen expansion resulting in more compressive strength
A cube is a special kind of prism.
yes! A cube is a type of prism. A prism is a subcategory of a cylinder. Then I cube is a type of cylinder
