Question

the Length breadth and the volume of a cuboid are 80 CM 60 cm and 19200 respectively find its height total surface area and the lateral surface area ​

Answer 1

Answer:

70

Step-by-step explanation:

length is 80 cm

breadth is 60cm

volume is 19200

laternal area is 2(bh+lh)

2h(l+b)

2h(80+60)

2h=140

h=140÷2=70

so height is 70

Answer 2

Answer:

Step-by-step explanation:

length of a cuboid = 80 cm

breadth of a cuboid = 60 cm

volume of a cuboid = lbh

19200 = 80 x 60 x h

h = 19200 / 80 x 60

h =  144 cm

TSA of a cuboid = 2(lb + bh + hl )

                              = 2( 4800+ 8640+ 11520)

                              =  36480

LSA of cuboid = 2h(l+b)

                        = 2 x 144 ( 80+60 )

                        = 40320
