Question

If the LSA of a cube is 1296m, then its TSA is​

Answer 1

Answer: 1944 m^2

Step-by-step explanation:

LSA of cube = 4a^2

But given LSA of cube= 1296 m^2

4a^2= 1296

a^2 = 1296/4

a^2 = 324

a = √324 = √(18×18)

a = 18,

So, Length (Side) of Cube=18

TSA of Cube = 6a^2 = 6(18^2)

= 6× 324 = 1944 m^2
