To find the value of "m", we first need to convert the height "l" from centimeters to meters.

Given: l = 175 cm

To convert from centimeters to meters, we divide by 100:

l = 175 cm = 175 / 100 = 1.75 meters

Now we can use the formula relating force (F), height (h), and mass (m):

F = 6h

Substitute the value of "h" with the converted height "1.75 meters":

F = 6(1.75)
F = 10.5 N

The value of force (F) is 10.5 N.

Now, we can use the formula relating force (F), mass (m), and acceleration due to gravity (g = 9.81 m/s^2):

F = mg

Substitute the value of F and solve for mass (m):

10.5 = m * 9.81
m = 10.5 / 9.81
m ≈ 1.07 kg

Therefore, the mass (m) of the object is approximately 1.07 kg.
