Question

Gas Tank- 11 in , 1.25 ft, 1.75 ft

The gas tank is 20% full. Use the current price of gas in your community to find the cost to fill the tank (1 gal = 231 in^3
Current price = 3.79

Answer 1

$45.48

Explanation:

Convert to inches

1.25 × 12 = 15

1.75 × 12 = 21

Since 11 is already in inches we don't have to change that.

Now from the formula: LWH

Therefore, we have:

V = 11 × 15 × 21

V = 3465

Now, from the given the gas tank is 20% full

Finding 20%:

3465 × 20 % = 693

Now subtract to find the other 80%

3465 - 693 = 2772

Since 1 gal = 231 in ³

2772/ 231 = 12

Now, 12 mulitply by the current price of gas given:

12 × 3.79 = 45.48

Hence, the cost to fill the tank is $45.48

Answer 2

$45.48

Explanation:

Given that:

Gas tank are 11 inches, 1.25 feet and 1.75 feet.

The gas tank is 20% full. Use the current price of gas in your community to find the cost to fill the tank (1 gal = 231 in³)

Current price = 3.79

Solution:

Formula: Volume = LWH

While,

L = Length

W = Width

H = Height

Since we, know that

Gas tank are 11 inches, 1.25 feet and 1.75 feet.

We have to convert either to inches or feet.

Note that: 1 feet = 12 inches

I will convert feet to inches

Thus,

1.25 × 12 = 15

1.75 × 12 = 21

Since 11 is already in inches we don't have to change that.

Now from the formula: LWH

Therefore, we have:

V = 11 × 15 × 21

V = 3465

Now, from the given the gas tank is 20% full

Finding 20%:

3465 × 20 % = 693

Now subtract to find the other 80%

3465 - 693 = 2772

Since 1 gal = 231 in ³

2772/ 231 = 12

Now, 12 mulitply by the current price of gas given:

12 × 3.79 = 45.48

Hence, the cost to fill the tank is $45.48
