Select the correct answer from each drop-down menu. Ronald is buying a rectangular chest to store his carpentry tools. The height of the chest, in feet, is represented by the function H(x) = x+6.

The area of the base of the chest, in square feet, is represented by the function A(x)= 20 square root x/ 3. In both functions, x represents the width of the

chest in feet.

To find a function that represents the volume of the chest, Ronald should ? Functions H(x) and A(x)

The function that represents the volume of the chest is V(x) =20x square root x/ 3 + ? square root x
