Final answer:
The pressure exerted by the block on the ground is calculated using the formula pressure = force/area, resulting in approximately 1.5278 N/cm².
Step-by-step explanation:
To calculate the pressure that the block exerts on the ground, we need to use the formula pressure = force/area. With a force of 220 newtons and the area of contact being the size of the base of the cuboid (12 cm by 12 cm), we can calculate the area in square centimeters (cm²).
The area A = length × width = 12 cm × 12 cm = 144 cm². Now using the formula for pressure (P):
P = F/A = 220 N / 144 cm² = 1.5278 N/cm² (rounded to four decimal places).
Therefore, the pressure exerted by the block on the ground is approximately 1.5278 N/cm².
