A cubic tank holds 1,000.0 kg of water. What are the dimensions of the tank in meters? Explain your answer.

• Physical Science -

The volume of a cube of length a (on each side) is a^3.

a^3 = 1000 in this case

Take the cube root of each side.

• Physical Science -

I left out a step. 1000 kg of water has a volume of 1 cubic meter or 10^6 cubic cm.

Write

V = a^3 = 1.000 m^3 and take the cube root of each side

a = 1.000 meter
