A model of a car is made to a scale of 1:40. The volume of the model is 45 cm square.
Calculate the volume of the car.
Give your answer in m square .

2025 m squared

Step-by-step explanation:

1:45

45

to get from 1 to 45, you times by 45.

to find the volume, times 45 by 45 for the second ratio

=2025 m squared

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

the answer to question 1 is -8, 28.
