Question

7.
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 1

the three dimensions of the room exactly is 75cm

Answer 2

Answer:

150m

Step-by-step explanation:

Given,

l=8.25m

b=6.75m

h=4.50

Perimeter of bottom and top = 2(l+b)

=2(8.25+6.75)

=2×15

=30m

Therefore, Bottom=Top=30m

Now,

Face of one and three=2(l+b)

• =2(8.25+4.50)
• =25.5m

Similarly,

Face of Second and fourth=2(b+h)

=2(6.75+4.50)

=22.5m

Therefore,

Total edge length=2(22.5+22.5+30)

=2(45+30)

=2×75

=150m
