The length, breadth and height of a room are 8.25m,6.75m and 4.50m respectively. Determine the longest tape which can measure the three dimensions of the room exactly.
Answers
Step-by-step explanation:
as we know
l= 8.25 m
b= 6.75 m
h = 4.50m
Now let's three combinations
perimeter of the bottom and top
= 2 ( l+ b )
= 2( 8.25 + 6.75 )
= 2 × 15
= 30 m
top = bottom = 30
Now face one and three
= 2( l + h)
= 2 ( 8.25 + 4.50 )
= 25.5 m
Now face two and forth
= 2( b+ h)
= 2 ( 6.75 + 4.50 )
= 22.5 m
Now totally edge length
= 2 ( 22.5 + 22.5 + 30 )
= 2 ( 45 + 30 )
= 2 ( 75 )
= 150 m

Answer:
here as we know
l= 8.25 m
b= 6.75 m

Now face two and forth

= 2 ( 6.75 + 4.50 )
= 22.5 m
Now totally edge length
= 2 ( 22.5 + 22.5 + 30 )
= 2 ( 45 + 30 )
= 2 ( 75 )
= 150 m => ANSWER
