How many cubic meters of soil can be excavated from a swimming pool 40 meters long, 20 meters wide and 2.5 meters deep? If each cubic meter of soil weighs 0.7T, how many times does it need to be transported by a 3.5t truck?

How many cubic meters of soil can be excavated from a swimming pool 40 meters long, 20 meters wide and 2.5 meters deep? If each cubic meter of soil weighs 0.7T, how many times does it need to be transported by a 3.5t truck?

Volume of soil = length × width × depth = 40 × 20 × 2.5 = 2000 cubic meters
It can dig up 2000 cubic meters of soil
Weight of soil = 2000 × 0.7 = 1400t
Times of transportation = 1400 △ 3.5 = 400
It takes 400 times

How many cubic decimeters are equal to one side?
It's a little difficult to do homework. Help to solve it

1 meter = 10 decimeters, so 1 cubic meter equals 1000 cubic decimeters

How many liters is one cubic meter of diesel oil equal to
How many liters is 1 cubic meter of diesel oil (No. o diesel oil, density 0.86)?
Does it have anything to do with the density of the liquid? Is every liquid the same?

It's not about density
It must be 1000 liters
1 cubic meter = 1000 cubic decimeters = 1000 liters
