The plans for a diving pool call for a rectangular pool that has a length of 30 meters, a width of 25 meters, and a depth of 5 meters. If the plans are changed to increase both the length and the width of the pool by 10%, what will be the increase, to the nearest 1%, in the volume of the pool?

#12 find the value of x. #13 find the value of the variable.
