Question

Find the total surface area of a cuboid of length,breadth and height as given below 6cm,5cm,4cm​

Answer 1

Answer:

148 cm^2

Step-by-step explanation:

TSA=2(lb+bh+lh)

=2(5×4+5×6+6×4)

=2(20+30+24)

2(74)

=148cm^2

Answer 2

Answer :-

• The total surface area of cuboid is 148cm².

Step-by-step explanation :

To Find :-

• The total surface area of cuboid

Given that,

• Length of cuboid = 6cm
• Breadth of cuboid = 5cm
• Height of cuboid = 4cm

Solution :-

As we know that,

Total surface area of cuboid = 2( lb + bh + hl ) sq. units,

Where,

• l = Length
• b = Breadth
• h = Height

Therefore,

=> 2 ( lb + bh + hl )

=> 2 ( 6*5 + 5*4 + 4*6 )

=> 2 ( 30 + 20 + 24 )

=> 2 ( 50 + 24 )

=> 2 ( 74 )

=> 2*74

=> 148

The total surface area of cuboid is 148cm².

More Information

Some more information related to cuboid :-

• Volume of cuboid = l × b × h cubic units.
• Diagonal of cuboid = √(l² + b² + h²) units.
• Total surface area of cuboid = 2(lb + bh + hl ) sq. units.
• Lateral surface area of cuboid = 2[(l + b) × h] sq. units.
• Area of four walls of a room = [2(l+b) × h] sq. units.
