The correct question is

Mr. Hopkins is building a sandbox for his children. It would cost $228 for the sand if he builds a sandbox with dimensions 9 ft by 6 ft. If Mr. Hopkins decides to increase the size to 13 1/2 ft by 8 ft but keep the same depth of sand, how much would the sand cost

step 1

Find the unit rate of the cost per square foot

Divide the total cost by the area

step 2

Find the area of the increased sandbox

we have

The area is equal to

step 3

Find the cost of the new sandbox

Multiply the area by the cost per square foot
