Question

the length and breadth of a height of a room are 8.25 6.75 and 4.15 respectively determine the longest tape which can measure the three dimensions of the room exactly​

Answer 1

Answer:

76.6

Step-by-step explanation:

as there are four lengths four breadths and four heights, so longest tape

=4(l+b+h)

=4(8.25+6.75+4.15)

=76.6

Answer 2

Question:

The length, breadth and height of a room are 8.25 m, 6.75 m and 4.50 m respectively. Determine the longest tape which can measure the three dimensions of the room exactly.

Answer:

• 150 m

Solution:

• Length of room = 8.25 m
• Breadth of room = 6.75 m
• Height of room = 4.50 m

Perimeter of length & breadth = 2(l + b)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(8.25m + 6.75m)

⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2(15)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 30

Top and Button = 30 m

Perimeter of length & breadth = 2(l + b)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(8.25 + 4.50)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(12.75)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 25.5 m

Perimeter of breadth & height = 2(b + h)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(6.25m + 4.50m)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(10.75)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 22.5 m

Now, totally edge of Length

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(22.5 + 25.5 + 30)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(45 + 30)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2(75)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 150 m
