Question

what is the length of the longest rod which can be placed in a box. of 80cm length, 40cm breadth and 60 cm height?​

Answer 1

✪ Dimension of the box:

◉ Length, l = 80 cm

◉ Breadth, b = 40 cm

◉ Height, h = 60 cm

Longest rod which can be placed in the given box is of length of the diagonal of the box,

Diagonal = √(l² + b² + h²)

☛ √(80² + 40² + 60²)

☛ √(6400 + 1600 + 3600)

☛ √11600

☛ ≈ 107.70

Hence, About 107.70 cm is the length of the longest rod which can be placed inside the box.

Answer 2

Step-by-step explanation:

Length = 80 cm

Breadth = 40 cm

Height = 60 cm

Length of rod = length +breadth

= 80 + 40 = 120 cm
