An automobile engine is has a displacement of 4.0l. what is the displacement in cubic inches?

240 in³

Explanation:

You want to convert litres ⟶ cubic inches

I would use the conversion sequence:  

litres ⟶ cubic centimetres ⟶ cubic inches

Recall that 1 L = 1000 cm³    Convert litres to cubic centimetres

4.0 × 1000/1 = 4000 cm³

Also, 1 in = 2.54 cm               Convert cubic centimetres to cubic inches

4000 × (1/2.54)³ = 240 in³

Displacement of automobile engine = 244.1 cubic inches

Step-by-step explanation:

We are given the displacement of an automobile engine to be 4.0L.

We know that:

1 liter = 61.0237 cubic inches

So assuming x cubic inches to be equivalent to 4 liters, we can write it as:

There, the displacement of an automobile engine in cubic inches is equal to  244.1 cubic inches.

i'm assuming that the correct answer is indeed the first one/ "a"..
