Answer:
Surface area = 39 yards²
Step-by-step explanation:
∵ the surface area of the pyramid = 1/2 pl + base area
Where p = perimeter of the base , l = slant height
∵ Area of the base = 3 × 3 = 9 yards²
∵ Perimeter of the base = 4 × 3 = 12 yards
∵ Slant height = 5 yards
∴ The surface area = 1/2 × 12 × 5 + 9 = 39 yards²
1. 64+28+21=113 sq. feet
2. 5x5=25 sq. ft.

Answer:
9 feet 1 inch
Step-by-step explanation:
So, to get the answer we want to add the heights of the boxes.
2 feet, 4 inches + 2 feet 11 inches = 4 feet 15 inches. 4 feet 15 inches + 3 feet 10 inches = 7 feet and 25 inches. 25 inches is equal to 2 feet and 1 inch, so we end up with 9 feet and 1 inch as our answer.
