One of the most known buildings in the
world are the Eiffel Tower – 324 m, the Liberty
Statue – 93 m, the Pisa Tower – 55,86 m.
The highest trees in the world, is in
California. In order to calculate its height
please subtract 312 of the aggregate amount of
Liberty Statue and Eiffel Tower .
To find out the growth rate of the small
willow, subtract 55,80 from the height of the
Pisa Tower.
World’s highest tree, from the Sequoia
National Park, California, General Sherman,
is about 2000 years old, which means that it is
an average sequoia, as there are sequoia trees
over 3.220 years old.
What year is the oldest tree?
In Crossville, Tennessee,
an American, Horace
Burgess, completed the
biggest house in the
world, with 80 rooms,

3.300 square meters.
World’s second largest tree is Helios, 114,1 m
high, followed by Icarus (113,1 m) and Daedalus
(110,8 m). Their location is secret so as to
prevent vandalism.
Calculate the height difference between the
first and second oldest trees, respectively the
first and the third oldest trees.
The wood was donated or recovered
from demolished houses, garages or
warehouses. He spent only 12.000 for the
nails.There is a solid tree in the middle and
five others supporting the other parts of the
building. The building has around
400 visitors weekly.
How many visitors have visited the house
so far?
World’s highest tree, General Sherman, is
in Sequoia National Park from California.
It is 83,8 meters high, 7,7 meters in diameter, and between 2.300 and 2.700 years old.
Its volume is 234 cubic meters more than
half of an Olympic swimming pool of 2.506
cubic meters. Calculate the tree volume.
Five of the six highest buildings in Europe
are in Moscow . The highest is Mercury City
Tower - 339 m, 75 floors.
The London Shard is 309,6 m high and has
87 floors.
The world’s highest tree is 115 m.
What floor (approximately) can a tree reach
in Moscow? But London?
Romania’s highest building is in
Bucharest, Sky Tower, is 137 m high and
36 floors. What floor would a Christmas
tree top reach if it is 63 m high from
Braşov area?
In 1964 a 4.862 year-old tree was cut down in
Nevada, USA. Another “still alive” tree is a
Chilean cypress from Alerce Andino,
National Park, aged 3.622. How much older is
the pine tree than the Matusalem tree?
How much time must the cypress still live to
reach this age?
The age of the world’s oldest tree, the
Matusalem pine, from the White Mountains,
California, was dated in 1957.
How old was it in 1957 as it germinated in
2832 B.C. ?
Tjikko tree, Sweden.
The age of the old Tjikko tree, from Sweden,
is 1910 when divided to 5.
Find out the age of the tree.
Romania’s highest building is in Bucharest,
Sky Tower, is 137 m high and 36 floors.
what is the height of the world’s second
highest tree which is 23 m shorter?
What floor (approximately) can Helios reach ?
A Chilean old tree is a 3622-year old cypress
tree. Find the age of the
Iranian Sarv-e-Abarkooh tree,
which is 378 years older.
The Taiwanese sacred Alishan tree, aged 3.000,
crashed on July 1, 1997 following heavy rain.
A 4862 year old pine tree from Nevada was cut
down in 1964 following its damage.
How long would the sacred tree have lived if it
had resisted to the present day?
What about the pine tree?
"The Senator" cypress tree from Florida is
about 3.500 years old, the world’s fifth oldest
trees. It is the oldest tree east of Mississippi.
Another South - American old tree is
Patriarca de Floresta, about 3.000 and
"General Sherman", a giant sequoia aged
2.700.
Make the age difference between the first
and the second, then the second and the
third tree.
One of the world’s oldes trees is Arbol del Tule
from Santa Maria del Tule, Oaxaca aged
between 1.200 - 1.300 and 11.3 m in diameter.
What is the diameter of the California tree
with 111.5 m height and 2,3 m shorter
(millimeters).
A real natural phenomenon, the tree of life is
2km away from Jebel Al Dukhan, Bahrain.
The locals believe that here there was the
Garden of Eden and 4015 tourists visit every
month this tree deeply rooted into the ground .
How many tourists visit this tree annually?
Weekly?
Major Oak is an important tree from
Sherwood forest, Nottinghamshire, England.
The oak is believed to be 1000, and in 1790,
Major Hayman Rooke included it is his
popular book about the Sherwood forest.
Hence the name of Major Oak. How long has
this tree been included in the book and how

The 800-year old baobab trees often exceed
30 m, and their crown is 11 m in diameter.
What is the height of the Californian tree
with 9 m in diameter and 81,5 m higher
(in millimeter).
If a baobab tree trunk retains 100.000
liters of water, surviving the draught,
how many liters of water can retain
three such trees?
Calculate the volume of water in cubic
meters.
6.4 million hectares are anually deforested,
shows a UN Report. Statistics show that our
planet loses 10 hectares of forest per minute in
the last 15 years due to transformation of
tropical forests into agricultural land, mostly in
South America and Africa.
How many hectares have disappeared in
the last 15 years?
