Among these figures, figure have the same volume

is there a photo that you can use to show what you mean?

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 is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
