Step-by-step explanation:
Given :-
The length, breadth and height of a room are 12 m, 15 m and 18 m respectively.
To find :-
Determine the length of longest tape which can measur all the three dimensions of the room exactly.?
Solution :-
Given that
Length of a room (l) = 12 m
Breadth of the room (b) = 15 m
Height of the room (h) = 18 m
To find the the length of longest tape which can measur all the three dimensions of the room exactly then we have to find the HCF of the three measures.
12 = 2×2×3
15 = 3×5
18 = 2×3×3
HCF = 3
Required length = 3 m
Answer:-
The length of longest tape which can measur all the three dimensions of the room exactly is 3 m
Used Concept:-
→ HCF = Heighest Common Factor
