Question

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

Answer 1

Answer:

6 m

Step-by-step explanation:

$surface \: \: area = 4 {s}^{2}$

s is side

$150 = 4 {s}^{2} \\ {s}^{2} = 37.5 \\ s = 6.1 \: m$

Answer 2

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
