For example if a researcher wants to find the average height of teenager of age group between 13 year and 15 years in Seattle, he will need the data of the population of height of teenager of age group between 13 year and 15 years in Seattle.

The world's tallest building is the Burj Khalifa in Dubai at 828 m tall. The CN Tower in Toronto is 553 m tall. Ryan wants to co

Taya2010 [7]

Answer:

Volume of Burj Khalifa Prism = 4000 $cm^2$

Volume of CN Tower Prism = 2671 $cm^2$

Step-by-step explanation:

Given

Height of Burj Khalifa = 828 m

Height of CN Tower in Toronto = 553 m

Base of rectangular prism is a square with sides 10 cm $\times$ 10 cm.

Height of Burj Khalifa prism = 40 cm

828 m is represented as 40 cm

$\Rightarrow 553 m$ is represented as $\frac{40}{828 } \times 553 = 26.71\ cm$

So, height of rectangular prism of CN Tower = 26.71 cm

Volume of a Prism is given by the Formula:

$V=Area\ of\ Base \times Height$

Base is a square, so Area of base = $Side^2$

Volume of Burj Khalifa Prism:

$V_B=10^2 \times 40 = 4000\ cm^2$

Volume of CN Tower Prism:

$V_C=10^2 \times 26.71 = 2671\ cm^2$

So, the answer is:

Volume of Burj Khalifa Prism = 4000 $cm^2$

Volume of CN Tower Prism = 2671 $cm^2$
