Question

The length breadth and height of a room are 8.25m,6.75m and 4.50m in respectively.find the length of the largest tape that can measure the three dimensions exactly

Answer 1

Answer:

Length = 8.25m

Breadth = 6.75m

Height = 4.50m

Let the 3 combinations,

=2(l+b)

=2(8.25+6.75)

=2 x 15

=30

The top and bottom are 30m

Second combination,

=2(l+h)

=2(8.25+4.50m)

=2 x 12.75

=25.5m

Third combination,

=2(b+h)

=2(6.25m+4.50m)

=2 x 10.75

=22.5m

Total length of the edge,

=2(22.5+22.5+30)

=2(45+30)

=2(75)

=150m
