The answer is 161.70 N.
EXPLANATION
To change from mass to weight multiply by gravity (9.8 m/s^2)
Fw = m * 9.8 m/s^2
Fw = 16.5 kg * 9.8 m/s^2 = 161.70 N.
2100/1 or 4200/2, could be either
Given:
The expression is

To find:
The value of the given expression closest to the whole number.
Solution:
We have,

Cancel out the common factors from each fraction.




Therefore, the value of the given expression is 1.
surface area= perimeter x height + 2b
s= pxh+2b
example: 18(8)+2(12)
explain: 18 is the perimeter and 8 is the height then you have to add the base times 2
