To solve for the total surface area of the figure, we need to find the surface area of each individual shape and add them together.

Given that we have a cylinder with a radius of 6 cm and a height of 5 cm, we can calculate the surface area of the cylinder:

Surface area of a cylinder = 2πr^2 + 2πrh
= 2π(6)^2 + 2π(6)(5)
= 2π(36) + 2π(30)
= 72π + 60π
= 132π
≈ 415.03 cm²

Next, we have a cone with a radius of 6 cm and a slant height of 8 cm, we can calculate the surface area of the cone:

Surface area of a cone = πr^2 + πrl
= π(6)^2 + π(6)(8)
= π(36) + π(48)
= 36π + 48π
= 84π
≈ 263.89 cm²

Therefore, the total surface area of the figure is approximately:
415.03 cm² + 263.89 cm² = 678.92 cm²

The closest answer choice to this calculation is 677.8 cm².

Apologies for the mistake in the previous response. Let's correct the calculation:

Total surface area = lateral surface area of the cylinder + base area of the cylinder + base area of the cone

Radius of the cylinder = 6 cm
Height of the cylinder = 5 cm

Lateral surface area of the cylinder = 2πrh
= 2π(6)(5)
= 60π
= 188.5 cm² (approximately)

Base area of the cylinder = πr^2
= π(6)^2
= 36π
= 113.1 cm² (approximately)

Radius of the cone = 6 cm
Slant height of the cone = 8 cm

Base area of the cone = πr²
= π(6)^2
= 36π
= 113.1 cm² (approximately)

Total surface area = 188.5 cm² (cylinder lateral area) + 113.1 cm² (cylinder base area) + 113.1 cm² (cone base area)
= 414.7 cm²

Therefore, the closest answer choice is 365.8 cm².
