Answer 1

Answer:

5 m

Step-by-step explanation:

surface area of cube is 6a^2.

6a^2=150m^2

a^2=25

a=5

Answer 2

Answer:

• 5 m.

Step-by-step explanation:

Given :

Surface area of a cube = 150 m².

To find :

Length of its edge.

Solution :

• Surface area of a cube = 6a²

⇒ 6a² = 150

⇒ a² = 150/6

⇒ a² = 25

⇒ a = √25

⇒ a = 5

∴ The length of its edge is 5 m.
