Can somebody Please Help

5425440 μm

Explanation:

From the question given above,

Length (in ft) = 17.8 ft

Length (in μm) =?

Next, we shall convert 17.8 ft to in. This can be obtained as follow:

1 ft = 12 in

Therefore,

17.8 ft = 17.8 ft × 12 in / 1 ft

17.8 ft = 213.6 in

Next, we shall convert 213.6 in to cm. This can be obtained as follow:

1 in = 2.54 cm

Therefore,

213.6 in = 213.6 in × 2.54 / 1 in

213.6 in = 542.544 cm

Finally, we shall convert 542.544 cm to μm. This can be obtained as follow:

1 cm = 10⁴ μm

Therefore,

542.544 cm = 542.544 cm × 10⁴ μm / 1 cm

542.544 cm = 5425440 μm

Therefore, 17.8 ft is equivalent is equivalent to 5425440 μm
