Question

A rectangular has sides that measure 9 centimeters by 12 centimeters by 23 centimeters. Joan filled the container to its brim with water. How much water must be pour out of the container so that only 2/3 of the volume of water is left in the container? Give your answer in milliliter a.

Answer 1

So you need to find the volume of the rectangular prism and the equation for that is V=l×w×h. If you plug those numbers in you'd get 9×12×23=2,484. If you multiply 2,484 by $\frac{1}{3}$ because you'd have to pour out $\frac{1}{3}$ of the water out so that it's only $\frac{2}{3}$ of the volume of water is left. 2,484×$\frac{1}{3}$= 828mm.
