### Lesson 7 MI/Vocab

Identify Solids

A.Identify the solid. Name the bases, faces, edges, and vertices.

### Lesson 7 Ex1

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 Ex1

Identify Solids

B.Identify the solid. Name the bases, faces, edges, and vertices.

### Lesson 7 Ex1

Answer: 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
