A fuel tank has a width of 18 inches, a height of 11 inches and a depth of 5 inches. What is the volume of the tank in m3
cupoosta [38]

Answer:

0.016 m³

Explanation:

Step 1: Given data

Width of the tank (w): 18 in

Height of the tank (h): 11 in

Depth of the tank (d): 5 in

Step 2: Calculate the volume of the tank in in³

The fuel tank is a cuboid. We can calculate its volume using the following expression.

V = w × h × d

V = 18 in × 11 in × 5 in

V = 990 in³

Step 3: Convert 990 in³ to m³

We will use the relationship 1 m³ = 61023.7 in³.

990 in³ × (1 m³ / 61023.7 in³) = 0.016 m³
