Question

The total surface area of a cube is 54 sq cm. What is the length of each of its edges?​

Answer 1

Answer:

total surface of a cube = 6a^2

6a^2=54

a^2=54/6

a^2=9

a=√9

a=3

therefore the length of each edge is 3cm

hope this helps

Answer 2

Answer:

3

Step-by-step explanation:

let length of each edges is a cm ,then

total surface area of a cube =6a²

ACQ,

6a²=54

à²=54/6

a²=9

a=3

Length of each edges is 3cm
