Remark

You can get it just by looking at the net. It has 6 squares. Each square has a side of 5 cm by 5cm. Find the area of 1 square and multiply by 6.

Step One

Find the area of one square.

Formula

Area = s^2

Solve

Area for 1 square = s^2 = 5^2 = 25 cm^2

Step Two

Find the area for six squares.

Area of the net = 6*Area of one square = 6 * s^2

6*s^2 = 6 * 25

Area = 150 cm^2

The Sears tower in Chicago is 1450 feet high. A model of the tower is 24 inches tall. What is the ratio of the height of the mod

miskamm [114]

The ratio of the model's height to actual height of tower is 1:725

Step-by-step explanation:

Given

Actual height of Sears Tower = $H_a$ = 1450 feet

Height of Model = $H_m$ = 24 inches

We can divide the actual height by the model's height to find the scale

Let z be the ratio of the height of the model to the actual height

$z = \frac{H_m}{H_a}\\z = \frac{24\ inches}{1450\ feet}\\z = \frac{12\ inches}{725\ feet}$

The ratio should be in same unit.

We know that

1 ft = 12 inches

Then

$z = \frac{1}{725}\\z=> 1:725$

Hence,

The ratio of the model's height to actual height of tower is 1:725
