144

Explanation:

The combined area of the two triangular faces is
`(4)(3)=12` cm².

The area of the back rectangular face is
`(3)(11)=33` cm².

The area of the bottom rectangular face is
`(11)(4)=44` cm².

The area of the slanted rectangular face is
`(5)(11)=55` cm².

Taking the sum of these areas, the total surface area is
`12+33+44+55=144` cm².
