Question

In a painting, The Great Pyramid of Giza is 45 centimeters tall.

If the pyramid is actually 146.5 meters tall, find the scale.

Answer 1

The scale is: 1 cm = 3.26 meter

Explanation:

Given

Height of Pyramid in Painting =
`H_p = 45 cm`

Actual Height of Pyramid =
`H_a = 146.5m`

In order to find the scale, we can find the ratio between actual height and height in painting.

The ratio can be found by dividing the actual height by height in painting

`Scale = (H_a)/(H_p)\\= (146.5)/(45)\\=3.25555 m/cm`

Rounding off to nearest hundredth

= 3.26

This means that the scale is:

1 cm = 3.26 meter
