hello you should get a life
I cannot think of any 2-d shape. The 3-d shape with four faces is a tetrahedron.
A shape with 11 sides and angles is called an 11-gon, or a hendecagon.
Hendecagon has 11 sides
Cube = 6 Sq base pyramid= 5 total= 11

a heptagon is a shape with 11 sides!
dodecagon * * * * * NO! That is 12 sides. 11 sides is a hendecagon.
Hendecagon has 11 sides
A shape that has 11 sides is called a hendecagon.
A geometric shape that has 11 sides is called a "hendecagon" or "undecagon." Both terms are acceptable.

Cube = 6 Sq base pyramid= 5 total= 11
A cube has 6 faces and each face is square, so the answer is 6*11*11 sq. cm.
elevenagon
It is an undecagon
