Question

Just wanted someone to check my work for this, because the question seems like it is too simple...

"A water canal has a rectangular cross section 3 meters wide and 2 meters deep. How much water is contained in a 30-meter length of the canal? How much water does it hold after 60% of the water has evaporated?"

volume = lwh
volume = (30)(3)(2)
= 180 m^3

60% of 180 = 108
180 - 108 = 72m^3

Is that all?

Answer 1

Looks right to me.

Answer 2

Great, thank you

Answer 3

You're welcome.
