Answer;

lateral surface area of cube= 324 cm^2

Step-by-step explanation:

given:

Total surface area of cube=486 cm

using surface area of cube(S.A) =6a^2

S.A=486                                                              (SA=486 ,given)

6a^2=486

a^2=486/6

a^2=81

a= square root 81

a=9

using lateral surface area(L.S.A) =4a^2

L.S.A=4*9^2

L.S.A=4*81

L.S.A=324cm^2
