Question

the dimensions of a room are 12m*7m*5m.find the diagonal of the room​

Answer 1

Answer:

here, l = 12m

b = 7m

h = 5m

diagonal = √ l² + b² + h²

= √ 12² + 7² + 5

=√144+49+25

= √218

≈ 14.18 CM

Answer 2

The value of the diagonal of the cuboidal room is 14.28m.

Step-by-step explanation:

Given:

The dimensions of the room:

Length=12m

Breadth= 5m

Height= 7m

To find:

The diagonal of the room

Solution:

The formula for finding the diagonal=

$\sqrt{l^{2}+b^{2}+h^{2} }$

Plugging in the values:

$\sqrt{12^{2}+7^{2}+5^{2} }$

=$\sqrt{144+35+25}$

=$\sqrt{204}$

=14.28m

Result:

Thus the value of the diagonal of the cuboidal room is 14.28m.
