A Truck Whose Bed Is 8 Feet Long, 5 Feet Wide, And 3 Feet High Is Delivering Sand In A Construction Site. How Many Trips Must The Truck Make To Delive

A truck whose bed is 8 feet long, 5 feet wide, and 3 feet high is delivering sand in a construction site. How many trips must the truck make to deliver 300 cubic feet of sand?

 

Answer:

no. of trips = 3

Step-by-step explanation:

A truck whose bed is 8 feet long, 5 feet wide, and 3 feet high is delivering sand in a construction site. How many trips must the truck make to deliver 300 cubic feet of sand?

Given: length (l) = 8 ft

           width (w) = 5 ft

           height (h) = 3 ft

           volume of sand to be delivered (Vs) = 300 cubic ft.

Required: number of trips for the truck to meet the required volume of sand

Solution:

Vt (volume of bed of truck) = l × w × h = (8 ft) ( 5 ft) (3 ft) = 120 cubic ft.

no. of trips = volume of sand / volume of bed of truck = 300/ 120 = 2.5

there is no half trip so we should round round it up

no. of trips = 3
