To determine which board can cover a space of 1 square yard, we need to calculate the area of the second and third boards that are provided in different measurements.
-
First Board:
- Area = 1 square yard = 1 square yard (this board directly fits the requirement).
-
Second Board (3 ft x 3 ft):
- First, convert feet to yards:
- 3 ft = 3/3 = 1 yard.
- Area = 1 yard x 1 yard = 1 square yard.
- First, convert feet to yards:
-
Third Board (36 in x 36 in):
- First, convert inches to yards:
- 36 inches = 36/36 = 1 yard.
- Area = 1 yard x 1 yard = 1 square yard.
- First, convert inches to yards:
Conclusion:
All three boards measure 1 square yard in area:
- The first board is already 1 square yard.
- The second board (3 ft by 3 ft) is equivalent to 1 square yard.
- The third board (36 in by 36 in) is also equivalent to 1 square yard.
Therefore, all three boards will cover all the space needed for the roof.
