phele
l = 30cm
B = 40cm
H = 20 cm
volume of cuboid =l×b×h
=(30×40×20) cubic cm
=24000 cubic cm
then,
there are 4 cuboid with same lbh
volume of 4 similar cuboid = 4×24000cubic cm
=96000 cubic cm
2)
CSA of cuboid =2( l+B ) h
= 2( 30 + 40 )20
=40 (70)
= 2800 square cm

3)
TSA Of cuboid = 2( lb + bh + hl )
=2 ( 30×40)+(40×20)+(30×20)
=2(1200)+(800)+(600)
=2(2600)
=5200 square cm
