Masha is making a scale diagram of the front face of an aquarium. The face is shaped like a rectangle.
 She uses a scale of 1 centimeter to 6 inches to draw the diagram. The actual length of the aquarium face is 5 feet, and its width is 2 feet. The perimeter of the scale drawing of the front face is 
 centimeters.

To find the perimeter of the scale drawing of the front face of the aquarium, we first need to convert the actual dimensions to the scale dimensions using the given scale of 1 centimeter to 6 inches.

### Conversion factors:
1 foot = 12 inches

### Actual dimensions in inches:
- Length: \( 5 \, \text{feet} \times 12 \, \text{inches/foot} = 60 \, \text{inches} \)
- Width: \( 2 \, \text{feet} \times 12 \, \text{inches/foot} = 24 \, \text{inches} \)

### Scale dimensions:
Since 1 centimeter on the scale drawing corresponds to 6 inches of the actual dimensions:
- Scale length: \( \frac{60 \, \text{inches}}{6 \, \text{inches/cm}} = 10 \, \text{cm} \)
- Scale width: \( \frac{24 \, \text{inches}}{6 \, \text{inches/cm}} = 4 \, \text{cm} \)

### Perimeter of the scale drawing:
The formula for the perimeter of a rectangle is:
\[
\text{Perimeter} = 2 \times (\text{Length} + \text{Width})
\]

Substitute the scale dimensions:
\[
\text{Perimeter} = 2 \times (10 \, \text{cm} + 4 \, \text{cm}) = 2 \times 14 \, \text{cm} = 28 \, \text{cm}
\]

Therefore, the perimeter of the scale drawing of the front face is \( \boxed{28} \) centimeters.
