Question

9) The length, breadth and height of a hall
are 9.76 m, 7.93 m and 1.83 m
respectively. Find the longest rod which
can measure the three dimensions an
exact number of times.​

Answer 1

Answer:

156.16 is the answer

Step-by-step explanation:

Given :

. Length of the hall = 9.76

. breadth of the hall = 7.93

. Height of the hall = 1.83

To find :

the longest rod which can measure the three dimentions an exact no. of time = ?

so,

L = 9.76

B = 7.93

H = 1.83

Perimeter of rectangle = 2×(l+b)

we get

= 2×( 9.76+7.93)

= 2 × 17.69

= 35.38 m

now ,

= 2×(l+h)

= 2×(9.76+1.83)

= 2× 11.59

= 23. 18 m

now,

= 2×(b+h)

= 2× (7.93+1.83)

= 2× 9.76

= 19.52 m

now total ,

= 2× (35.38 + 23.18 + 19.52)

= 2× 78.08

= 156.16
