Answer 1

Answer:

let we consider it as F, V, E

Step-by-step explanation:

case 1: the given cuboid has:

1. number of faces (f)=6
2. number of vertices (v)=8
3. number of edges (e)=12

we have,

F+V=6+8=14

F+V-E=14-12=2

F+V-E=2

case 2:[a part is sliced off]

we have:

1. number of faces (f)=7
2. number of vertices (v)=10
3. number of edges (e)=15

also,

F+V=7+10=17

F+V-E=17-15=2

F+V-E=2
