Answer:
7/15 Hope it helps
Step-by-step explanation:
2 yards = 6 feet
6 times 5 is 30
30 ft squared
Let Surface Area A, a the base edge and h the height:
A = a²+2a√(a²/4+h²)
h=?
pythagorean theorem:
h²=c²-a²
h=√(c²-a²)
h=√(8²-(.7/2)²)= 8
plug it in the above equation A= 11.7ft²
So A is correct
Answer:
20
