1.18. A fish tank has a base, B, with an area, in square inches, modeled by B(x) = 2x + 6x + 4.

The height, H, in inches, is modeled by HX) = x+3. Find the equation that models the fish tank's

volume, V, in cubic inches.

A. V(x) = 2x + 7x + 7

B. V(x) = 2x2 + 5x + 1

C. V(34) = 2x + 12x? +22x + 12

D. V(x) = 2x3 + 8x + 10x + 4
