Answer:

54 yd²

Step-by-step explanation:

The surface area of the prism is the sum of the areas of its faces. Opposite faces have the same area, so we can write the formula as ...

SA = 2(LW +WH +LH) = 2(LW +H(L +W))

Filling in the numbers, we have ...

SA = 2(6·3 +1(6 +3)) = 2(18 +9) = 54 . . . . square yards

The area is 54 square yards.
