Answer 1

Answer:

measurements=600cm,450cm,80cm

Volume of cuboid=l×b×h

=600×450×80

=21600000cm³

=21.6m³[1cm³=1×10^-6]

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

=2(600×450+450×80+80×600)

=2(270000+36000+48000)

=2(354000)

=708000cm²

=70.8m²[1cm²=0.0001m²]

LSA of cuboid=2(l+b)h

=2(600+450)80

=2(1050)80

=160×1050

=168000cm²

=16.8m²

Answer 2

1. 21.6m³

2. 70.8m²

3. 16.8m²

Step-by-step explanation:

• Volume of cuboid=(l)(b)(h)

=600×450×80

=2,16,00,000cm³

=21.6m³ (As we know that each centimetre is equal to 1×10^-6 m³)

• TSA of cuboid=2(lb+lh+bh)

=2(600×450+450×80+80×600)

=2(2,70,000+36,000+48,000)

=2×3,54,000

=708000cm²

=70.8m² (As we know that each centimetre square measures equal to 0.0001 metre square)

• LSA of cuboid=2lh+2bh

=>2(600+450)80

=>2(1,050)80

=>160x1,050

= 1,68,000cm²

=>16.8m²
