Question

Questions are ;1.)If the net were folded and assembled, What type of polyhedron would it make?2.) What is the surface area of the polyhedron? Explain your reasoning

Answer 1

1) If we assemble the polyhedron we would have the shape of a triangular prism

2) we have the following:

`\begin{gathered} A=p\cdot h+2B \\ p=3+4+5=12 \\ h=6 \\ B=(3\cdot4)/(2)=6 \\ A=12\cdot6+2\cdot6 \\ A=72+12 \\ A=84 \end{gathered}`

Therefore, the area is 84 cm^2
