Find the surface area of the rectangular prism.
6 yd
3 yd
1 yd
1 answer:
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.
