Problema Solution
An excavation crew digs a hole in the ground measuring 60 yd x 50 ydx 8 yd to facilitate a basement for an office building. Five dump trucks, each with a capacity of 20 yd^3, are used to haul the material away. How many trips must each truck make to remove all the material?

We will assume the whole is in the shape of cuboid with dimensions: 60 yd x 50 yd x 8 yd
Then the volume of the cuboid is:
V = 60*50*8
V = 24,000 yd^3
Let 'x' represent the number of trips that each truck must take to remove all the material:
5*20*x = 24,000
100x = 24,000 divide both sides by 100
x = 240 times
Each truck must make 240 trips.
