Question

find area of a cuboid whose height=2m Length=2.10m Breath=1.5m? ​

Answer 1

Answer:

Area of cuboid = l*b*h

So, Area = 2m * 2.1m * 1.5m = 6.3$m^{3}$

Answer 2

Correct Question :

• Find surface area of cuboid whose height = 2m , Length = 2.10m and breadth = 1.5m

Answer :

• Surface area of cuboid is 20.7m²

Given :

• Height = 2m
• Length = 2.10m
• Breadth = 1.5m

To find :

• Surface area of cuboid

Solution :

Given

• Length = 2.10m
• Breadth = 1.5m
• Height = 2m

We know That,

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

Where,

• l is length
• b is breadth
• h is height

⤍ Surface area of cuboid = 2(lb +bh + lh )

⤍ Surface area of cuboid = 2(2.10 × 1.5) + (1.5 × 2) + (2.10 × 2)

⤍ Surface area of cuboid = 2(3.15) + (3) + (4.2)

⤍ Surface area of cuboid = 2(3.15 + 3 + 4.2)

⤍ Surface area of cuboid = 2(10.35)

⤍ Surface area of cuboid = 20.7m²

Hence, Surface area of cuboid is 20.7m²
