Question

A scale model of a sculpture has a scale of 3 : 71.
The height of the model is 21 cm.
Find the height of the actual sculpture.
Give your answer in m.​

Answer 1

Step-by-step explanation:

From the given drawing, figure out the actual length of the wall at 1:1. To do so, multiply the drawn length by the scale factor. ...

Now that you know the actual length of the wall in reality, you can rescale it to any of your chosen scales. So, to get to 1:500, simply divide the length (24m) by 500.

Answer 2

Answer:

Height of the sculpture is 4.97 m

Step-by-step explanation:

Since, the scale model of the sculpture is 3/71

Height of the sculpture = 21 cm

Let the Actual height of the sculpture be x.

Therefore,

21/x = 3/71

=> 3x = 71×21

=> x = 71×21/3 = 71×7 = 497 cm = 4.97 m
