the volume of cube will be equal to the volume of cuboid.
so 50×27×20=a cube
so 27000= a cube
a = 30
=> lateral surface area of cube = 6×side square,
=> 6× 30×30
=>5400cm

ar of cuboid = ar of cube
l×b×h=a^3
50×27×20 = a^3
27000 = a^3
a = √27000
= 30cm
LSA of cube =4×a
= 4×30×30
= 3600cm^2
l×b×h=a^3
50×27×20 = a^3
27000 = a^3
a = √27000
= 30cm
