Answer:
False
Explanation:
Given:
9 inches = 9*2.5 cm = 22.5 cm
1 m = 100 cm
Height of each mattress = 22.5 cm
Number of mattresses = 7000
Total height of the stack of mattresses = 22.5cm*7000 = 157500 cm
1 m = 100 cm
157500 cm = 157500/100=1575 m
3 times the height of the CN Tower = 3*553 m = 1659m
Therefore, the stack of mattresses is only 1575 m high, which is less than 1659 m. Hence, the company's claim is false.
