How many edges does a solid with 11 faces and 11 vertices have?

Rzqust [24]

Answer:

20

Step-by-step explanation:

Given: F = 11, C = 11, E=?

By Euler's formula, we have:

$F + V - E = 2 \\ \therefore \: 11 + 11 - E = 2 \\ \therefore \:22 - E = 2 \\ \therefore \:22 - 2 = E \\ \huge \red{ \boxed{\therefore \: E = 20}}$

Hence, the solid will have 20 edges.

A number $x$ is equal to $7\cdot24\cdot48$. What is the smallest positive integer $y$ such that the product $xy$ is a perfect cu

Wewaii [24]

Take the prime factorization of $x$ .

$x = 7\times24\times48 = 7\times(2^3\times3)\times(3\times2^4) = 2^7\times3^2\times7$

If $xy$ is a perfect cube, then the smallest $y$ that makes this happen is $y=2^2\times3\times7^2 = \boxed{588}$ . We "complete" the cube by introducing just enough factors to get each prime power to be a multiple of 3.
