Question

verify Euler's formula for decagonal pyramid​

Answer 1

Here is ur answer mate!!

Answer

In a decagonal pyramid, number of sides of base is 10.

∴ Number of faces (F) = 10 + 1 = 11

Number of vertices (V) = 10 + 1 = 11

Number of edges (E) = 10 × 2 = 20

Now F + V = 1

1 + 11 = 22

Also E + 2 = 20 + 2 = 22

∴ F + V = E + 2
