The force required to break concrete depends on various factors such as the type of concrete, its age, and the specific conditions of the concrete. In general, the compressive strength of concrete is measured in pounds per square inch (psi). For typical concrete mixes, the compressive strength can range from about 2,500 psi to over 10,000 psi. Therefore, the force required to break concrete can vary widely, but it typically takes thousands of pounds of force to break through concrete.

Dependant on if you have additives with the concrete and how much water is in the mix. In general concrete will achieve 80 - 90 percent strength within in 24 hours
That may be strength specific and will be subject to air entrainment
Solving a Rubik's Cube does not require a specific IQ level. It mainly depends on practice, patience, and understanding of the cube's algorithms.
The weight of concrete is determined by its density, which is typically around 150 lbs/ft³. However, the density of concrete can vary depending on the type and amount of aggregate used, as well as the water-to-cement ratio. Additionally, the weight of concrete can also be affected by the compressive strength of the concrete, with higher strength concrete often weighing more than lower strength concrete. Therefore, the weight of 6,500 psi concrete can vary, but it is typically around 150 lbs/ft
The force required to destroy a 4x4x4 stone marble cube depends on the material's compressive strength, which varies by type of marble but typically ranges from 70 to 140 MPa (megapascals). To calculate the force needed to break the cube, multiply the compressive strength by the cross-sectional area of the cube's face (16 cm²). Thus, the force could range from approximately 1,120 to 2,240 kilograms-force, depending on the specific type of marble and its condition.
The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.
