Question

PLEASEEEE HELP URGENT

Answer 1

7.1 cm

Explanation:

The diagonal of a cube connects two opposite corners.

You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.

Let the length of the edge be s.

a^2 + b^2 = c^2

`s^2 + 10^2 = (√(150))^2`

`s^2 + 100 = 150`

`s^2 = 50`

`s = √(50)`

`s = 5√(2)`

s = 7.1

Answer: 7.1 cm
