Question

The surface area of a cube is 150 cm^2. What is the area of one of the faces?

Answer 1

Answer:

according to question :-

total surface area of cube = 6a^2

150 = 6a^2

150/6 = a^2

25 = a^2

√25 = a

5 = a

now area of its one face = a^2 = 5^2 = 25 cm ^2

hope you understand plz thank my answer

Answer 2

Answer:

Step-by-step explanation:

Surface area of cube = 6×side^2 or 6a^2 , where 'a' is the side of cube

Given: Surface area 150cm^2

So , Surface area of cube(150cm^2) = 6a^2

=> 150 = 6a^2

=> 150/6 = a^2

=> 25 = a^2

=> a = √25

=> a = √5×5

=> a = 5 cm

Hence , one of the faces of the cube is 5cm.
