Question

if the tsa of cube is 54 x square then find LSA​

Answer 1

Answer:

Step-by-step explanation:

TSA of cube = 6a^2

Therefore 6a^2 = 54

a^2 = 54/6

a^2 = 9

a = 3

now LSA = 4a^2

-> 4a^2

-> 4*3^2

-> 36

Answer 2

Answer:

T.S.A OF CUBE = $6a^{2}$

$6a^{2} =54x^{2} \\a^{2} =9x^{2} \\a=\sqrt{9x^{2} } \\a=3x$

L.S.A OF CUBE = $4a^{2}$

$4a^{2} =4(3x)^{2} =36x^{2}$
