Answer 2

Answer:

Volume=81m^3

Volume=81m^3Lateral surface area=37.8m^2

Volume=81m^3Lateral surface area=37.8m^2Total surface area=217.8m^2

Step-by-step explanation:

Length=15m

Breadth=6m

Height=9dm

1dm=10cm

100cm=1m

1cm=0.01m

10cm=0.1m

so, if 10cm=0.1m

but 10cm=1dm

Therefore 1dm=0.1m

Volume=l×b×h

=15m×6m×0.9m

=81m^3

Lateral surface area=2(l+b)h

2(15m+6m)0.9m

2(21m)0.9m

=37.8m^2

Surface area=2(lb+bh+HL)

=2(15×6+6×0.9+0.9×15)m^2

2(90+5.4+13.5)m^2

=2×108.9m^2

=217.8m^2
