The value of the x will be 25. The force involved vertically to the surface of an object per unit area is pressure.
What is pressure?
The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure.
The given data in the problem is;
The base of the block of metal is a rectangle of 20 cm by x cm.
The block exerts a force of 1500 newtons on the ground. The pressure on the ground is 3 newtons/cm²
The area of the rectangle;
A = L × B
A=20 × x
[tex]\rm P = \frac{F}{A}\\\\ 3 N / cm^2 = \frac{1500 N}{20 \times x } \\\\ x= 25[/tex]
Hence the value of the x will be 25.
