Answer 2

Answer ::

• The length of cuboid is 6cm.

Step-by-step explanation ::

To Find :-

• The length of cuboid

Solution :-

Given that,

• Breadth of cuboid = 2cm
• Height of cuboid = 7cm
• Volume of cuboid = 84cm³

Figure :-

• Refer the attachment.

As we know that,

Volume of cuboid = lbh

Where,

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

➛ Length × breadth × height = 84

➛ Length × 2 × 7 = 84

➛ Length × 14 = 84

➛ Length = 84/14

➛ Length = 6

The length of cuboid is 6cm.

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.
