Question

the surface area of a cubeoid 12m long and 4m broad is 192m square.find its height​

Answer 1

Answer:

l*b*h =192

12*4*h=192

48*h=192

h=192/48

h= 4

Answer 2

Answer:

T.S.A. of cuboid = 2(lb+bh+lh)

192 = 2( 12×4+4×h+12×h)

192 = 2(48+4h+12h)

96 = 48+4h+12h

96-48 = 16h

48 = 16h

h = 48/16

h = 3 mtr

I hope this answer is correct...
