Answer 1

As the perimeter of 1 face is 20cm

Let each side of cube be s cm.

As we know all sides of cube are equal So,

perimeter of 1 face of cube=4(s)

20=4s

s=20/4

s=5 cm

Hence each side of cube measures 5 cm.

Tsa of cube=6s^2

=>6(5)^2

=>6(25)

=>150 cm^2

I hope it will help u buddy.

Answer 2

Answer:

Step-by-step explanation:

if the perimeter of a face of a cube is 20cm the length of its side will be ,5cm

as we know area of a cube = 6a²,so

                                               =6*5²

                                               =6*25

                                               =150cm^2
