Answer:

506.7 cm²

Step-by-step explanation:

The amount of cardboard needed would be the surface area of the cone,

S= pi(r)(l+r) where r is the radius and l is the slant height.

You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.

Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²
