Question

the length breath and height of cuboid is 9 2 1 then find the length of diagonal​

Answer 1

Answer:

l = 12m , b = 9cm , h = 8cm we know, Length of diagonal of cuboid = √(l2+h^2+b^2) = √(144 + 81 + 64) = √(289) = 17m

Answer 2

Answer:

√86 units

Step-by-step explanation:

Given there is a rectangle.

It's dimension are :-

• Length, l = 9 units
• Breadth, b = 2 unuts
• Height, h = 1 unit

To find the length of diagonal.

We know that,

Diagonal of a cuboid is given by,

=> d = √(l^2 + b^2 + h^2)

=> d = √(9^2 + 2^2 + 1^2)

=> d = √(81+4+1)

=> d = √86

Hence, length of diagonal is √86 units.

Some formula:-

• TSA of cuboid = 2(lb+bh+hl)
• LSA cuboid = 2(l+b)h
