the lateral area is 466-2*98 = 270 u^2
So of the prism has length z, and the bases have perimeter p, then
pz = 270
Looking at the choices, it appears that z=10, so p=27
6+9+12 = 27, so I like (D)
The base of a right Triangular prism has an area of 98 m². If the total surface area of the prism is 466 square units, which of the following are possible areas for the faces of the prism?
