Question

Find the side of a cube whose surface area is 150² m​

Answer 1

Each edge will be 5 m long

There are 6 identical square faces
Area of each face = 150 / 6 = 25 m^2
Edge length = sr(25) = 5 m

Answer 2

6 m

Explanation:

`surface \: \: area = 4 {s}^(2)`

s is side

`150 = 4 {s}^(2) \\ {s}^(2) = 37.5 \\ s = 6.1 \: m`
