Problem 1: plants
In the United States, there is a giant sequoia tree that is 84-meters tall. The Eiffel Tower in Paris is 324-meters tall.
How much taller than the sequoia tree is the Eiffel Tower?
Problem 2: plants
Pacific giant kelp (a seaweed) can grow 48 centimetres in just one day. Some giant kelp grow to a length of 60 metres.
How many days would it take for the kelp to grow this long?
Problem 3: plants
In the Perfect Pine plantation, there are 45 rows of pine trees. Each row has 112 trees.
When a tree is 30 metres tall, it is cut down to make a timber pole. What is the total length of all the timber poles that can be cut from the plantation?
Problem 1: animals
A 130-tonne blue whale weighs about the same as 26 male African elephants.
If all the elephants weighed the same amount, how much would one African bull elephant weigh?
Problem 2: animals
The wingspan of a jumbo jet is 60 metres. That's five times the wingspan of a flying dinosaur that lived about 72 million years ago.
What was the wingspan of the flying dinosaur?
Problem 3: animals
At birth, a Nile crocodile is about
25-centimetres long. It can grow to become a 500-centimetre-long adult.
If a 50-centimetre-long human baby grew in the same proportion, how tall would the adult human be?
