Question

Q1. Verify the Euler's formula for cube.
Q2. state true or false -
1. Compound interest is calculated on the amount of the previous year.
2. If the interest is compounded quarterly then there are 2 conversion periods in a year.
Q3. Amount = .......................+ .principal​​

Answer 1

Answer:

are you in class 8

Step-by-step explanation:

1. vertex + face = edges +2

2. 1 true

2 false

3. interest

Answer 2

Answer:

V - E + F = 2; or, in words: the number of vertices, minus the number of edges, plus the number of faces, is equal to two. ... V - E + F = 12 - 30 + 20 = 32 - 30 = 2, as we expected. Euler's formula is true for the cube and the icosahedron.
