SAT Question f7e626b2: Area and Volume answer and explanation with Desmos solution

Choice D is correct. The surface area is found by summing the area of each face. A right rectangular prism consists of three pairs of congruent rectangles, so the surface area is found by multiplying the areas of three adjacent rectangles by $2$ and adding these products. For this prism, the surface area is equal to $2\times (4\times 5)+2\times (5\times 6)+2\times (4\times 6)$, or $2\times 20+2\times 30+2\times 24$, which is equal to $148$.
