The formula for the surface area of a cylinder is:

A = 2πr² + 2πrh

where r is the radius of the base and h is the height of the cylinder.

Given that the diameter of the base is 1.4 m, the radius (r) is half of the diameter, so:
r = 0.7 m

Given that the height (h) is 0.6 m, we can plug these values into the formula:
A = 2π(0.7)² + 2π(0.7)(0.6)

A = 2Ï€(0.49) + 2Ï€(0.42)
A = 0.98Ï€ + 0.84Ï€
A = 1.82Ï€

Therefore, the exact surface area of the cylinder is 1.82Ï€ square meters.
