LEVEL - 1
1. A cuboid is 20m x 10m x 8m. Find the
length of its diagonal.
A) 22.75 B) 23.75 C) 10.25 D) 12.25​

Answer 1

Answer :-

Given :-

• Dimensions of cuboid :- 20 m × 10 m × 8 m

To Find :-

• Length of diagonal

Solution :-

We know that,

Length of diagonal of cuboid = √( l² + b² + h² )

Here, we are given dimensions of cuboid. So, by simply substituting the value in above formula, we can find length of diagonal.

→ Diagonal = √ 20² + 10² + 8²

→ D = √ 400 + 100 + 64

→ D = √ 564

→ D = 2 √ 141

→ D ≈ 23.75

Length of diagonal = 23.75 m
