Question

the length ,bread the length breadth and height of a room are 12 and 18 respectively determine the the longest type which can measure all the three dimensions of the room exactly​

Answer 1

Step-by-step explanation:

question is incomplete

value of lenght and breadth is given but height is not given.

we have to find the H. C. F of lenght, breadth height.

If the height is the multiple of 6

the must be 6

Answer 2

CORRECT QUESTION :-

The length, breadth and height of a room are 12 cm, 18 cm and 15cm respectively. The longest tape which can measure the three dimensions of the room exactly.

SOLUTION :-

=>To find the length of the longest tape which can measure the three dimensions of the room, we need to find the H.C.F of length, breadth and height of the room, i.e. 12, 18 and 15cms respectively.

=>Let us factorise all three given dimensions.

12 = 2 × 2 × 3

18 =2 × 3 × 3

15 = 3 × 5

=>Hence, 3, are the common prime factors here.

=> So, H.C.F = 3 .

=>Therefore, we need 3cm longest tape to measure the three dimensions of the room.
