If so where did I go wrong.

A triangular prism has a height of 12 m. What is the surface area of the prism if its bases are right triangles w/ legs 3 meters and 4 meters?

My answer is:

C^2 = 3^2 + 4^2

C^2 = 9 + 16

C^2 = 25

C= 5

P= 4 + 3 + C

P= 4 + 3 + 5

P= 12

B = 1/2 bh

B = 1/2 (4)(3)

B= 1/2 (12)

B = 6

L = Ph

L= 12 (12)

L= 144

S= L + 2B

S= 144 + 2 (6)

S= 144 + 12

S= 156 m

Thank you for the help.
