A car company sells a scale model to of the size of one of its cars.
Complete the following table.
Scale Model
Real Car
2
Area of windscreen (cm)
135
V25
[3]
3
Volume of storage space (cm)
408000

Answer 1

Answer:

$w = 13500$ --- real windscreen

$v = 408$ --- scale volume

Step-by-step explanation:

Given

$k = \frac{1}{10}$ --- scale factor

See attachment

Required

Complete the table

To get the windscreen (w) of the real car, we do the following computation

$w = \frac{w_{scale}}{k^2}$

This gives:

$w = \frac{135}{(1/10)^2}$

$w = \frac{135}{1/100}$

$w = 13500$

Next, the volume (v) of the scale mode

We make use of the following computation

$v = v_{real} * k^3$

So, we have:

$v = 408000 * (1/10)^3$

$v = 408000 * 1/1000$

$v = 408$
