$Answer: \\ A - 20\%A = A - 0.2A = 0.8A \\ 0.8A + 20\%0.8A = 0.8A + 0.2 \times 0.8A = 0.8 + 0.16A = 0.96A$

A rectangular has sides that measure 9 centimeters by 12 centimeters by 23 centimeters. Joan filled the container to its brim wi

Svet_ta [14]

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.
