The surface area (A) of a cylinder can be calculated using the formula:

A = 2πrh + 2πr²

where:
r is the radius of the base of the cylinder,
h is the height of the cylinder.

Given that the radius r = 2.0 cm = 20 mm (since 1 cm = 10 mm) and the height h = 10.0 cm = 100 mm, we can substitute these values into the formula:

A = 2π(20 mm)(100 mm) + 2π(20 mm)²
A = 40000π mm² + 800π mm²
A = 40800π mm²

Therefore, the surface area of the solid cylinder is 40800π mm².
