Answer:
There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.
Given that length = 14 cm, width = 7 cm, and height(which was not mentioned in the question) is 1.66 cm, we are tasked to f<span>ind the lateral area and the surface area of the box.
To find the lateral area, we need to add the area of the sides of the 3D figure.
L = 2(1.66)(14) + 2(1.66)(7)
=46.48 + 23.34
=69.72 </span><span> ≈ 70 cm^2
</span>To find the surface area,
SA = 2(1.66)(14) + 2(1.66)(7) + 2(14)(7)
=46.48 + 23.24 + 196
=265.72 ≈ 266 cm ^2
The answers are <span>70cm^2 and 266cm^2.</span>
