Question

Find volume and surface area of a cuboid whose dimension are l=10cm ,b=8cm ,h=6cm

Answer 1

vol. of cuboid=l×b×h
=10×8×6
=80×6
=480 cubic cm

surface area of cuboid=2lh+bh+2lb
=2(10×6)+2(8×6)+2(10×8)
=2(60)+2(48)+2(80)
=120+96+160
=376 square cm

Answer 2

Answer:

Answer

vol. of cuboid=lxbxh

=10x8x6

=80x6

=480 cubic cm

surface area of cuboid=21h+bh+21b

=2(10x6)+2(86)+2(108)

=2(60)+2(48)+2(80)

=120+96+160

=376 square cm..
