1.	The diagonal of cuboid r l=8,b=4,h=20
Answer» Answer : Diagonal of cuboid is 21.9 Given : Length = 8 Breadth = 4 HEIGHT = 20 To FIND : Diagonal of cuboid Solution : As we know that, Diagonal of cuboid = √L² + b² + h² Where, l is length b is breadth h is height 》Diagonal of cuboid = √l² + b² + h² 》√(8)² + (4)² + (20)² 》√64 + 16 + 400 》√280 》21.9 Hence , Diagonal of cuboid is 21.9 More Explanation : Lateral surface area of cuboid = 2h(l + b) Total surface area of cuboid = 2(lb + bh + lh) Volume of cuboid = lbh Where , l is length , b is breadth and h is height

Answer»

Answer :

Diagonal of cuboid is 21.9

Given :

Length = 8
Breadth = 4
HEIGHT = 20

To FIND :

Diagonal of cuboid

Solution :

As we know that,

Diagonal of cuboid = √L² + b² + h²

Where,

l is length
b is breadth
h is height

》Diagonal of cuboid = √l² + b² + h²

》√(8)² + (4)² + (20)²

》√64 + 16 + 400

》√280

》21.9

Hence , Diagonal of cuboid is 21.9

More Explanation :

Lateral surface area of cuboid = 2h(l + b)
Total surface area of cuboid = 2(lb + bh + lh)
Volume of cuboid = lbh
Where , l is length , b is breadth and h is height
