Suppose the total volume of sand on the beach is 1,278m. What will the volume be after 24 hours of erosion?

Let's assume that the erosion rate is "X/hour". The total volume of sand on a beach after 24 hours would be,

= total sand volume - (erosion rate per hour * 24)

= 1,278m - (X/hour * day)

Explanation:

Now assume that the erosion rate is 1 m per hour. Therefore, in 24 hours would be,

= 1,278m - (1/hour * 24)

= 1,278 - 24

= 1254 m.
