Question

having:
1. Find the volume, the total surface area and the lateral surface area of a rectangular solid having:
length = 5.6 dm, breadth = 2.5 dm and height = 1 m.​

Answer 1

Answere:

Volume of the rectangular solid = 27.2 m³

Total surface Area of the rectangular solid = 61.85 m²

Lateral surface Area of the rectangular solid = 14.9 m²

Explanation:

• Length of the rectangular solid = 8.4 m

• Breadth of the rectangular solid = 6.4 m

• Height of the rectangular solid = 50 cm

Here all measurements are not in same Unit System

So, Convert measurement of height from CGS system to SI unit system.

We know that,

1cm= 1/100

So, multiple measurements of height with 1/100

⟹Height=50 × 1/100

⟹Height= 0.5m

Volume of cuboid = Length × Breadth × Height

= 8.5 × 6.4 × 0.5

= 27.2m³

So, Volume of the rectangular solid = 27.2 m³

_________________________________________

Total surface area of cuboid = 2(lb + bh + lh)

= 2(8.5(6.4)+6.4(0.5)+8.5(0.5.))

= 2(54.4+3.2+4.25)

= 61.85

So, Total Surface Area of the rectangular solid = 61.85 m²

__________________________________________

lateral surface area of the cubiod = 2h(l+b)

2 × 0.5(8.5 + 6.4)

=1(14.9)

=14.9m²

So, Lateral Surface Area of the rectangular solid = 14.9 m²

Please guys thanks my answer

Answer 2

volume of rectangular solid = l×b×h

= 5.6×2.5×1

=140.0

=140 is a final answer
