Answer: rectangular prism;Bases: rectangles EFHG, ABDCFaces: rectangles FBDH, EACG, GCDH, EFAB, EFGH, ABCD

Vertices:A, B, C, D, E, F, G, H

Identify Solids

The bases are rectangles. This solid is a rectangular prism.

Lesson 7 Ex1Answer: hexagonal prism;Bases: hexagon EFGHIJ and hexagon KLMNOPFaces: rectangles EFLK, FGML, GHMN, HNOI, IOPJ, JPKE

Vertices:K, L, M, N, O, P, E, F, G, H, I, J

Identify Solids

The bases are hexagons. This solid is a hexagonal prism.

Lesson 7 Ex1The base is a circle and there is one vertex. So, it is a cone.

Answer:Base: circle TVertex:Wno faces or edges
