2​

Answer 1

Answer:

Ans : 256 cm^2

Step-by-step explanation:

One face is equal to four sides. Let ‘a' be side of a cube .

Perimeter (4a ) = 32

4a= 32

a = 32/4 = 8 cm.

Lateral surface Area is 3 dimensional one. LSA is the area of all sides not including the base & top sides.

LSA = 4a^2

4a^2 = 4* 8*8

= 256 cm^2.

Ans : 256 cm^2.
