Answer:
Step-by-step explanation:
volume = area of base * height = area of base * 9 = 72
-> area of base = 72/9 = 8
let a,b,c be the length of sides of isosceles right triangle base
we have a = b and a*b/2 = 8 ft2
-> a*a/2 = 8ft2
-> a*a = 16
-> a=4ft=b
have c^2 = a^2 + b^2 = 16 +16 = 32
-> c = 
= 5.656 ft
Since i dont know that is DF, i calculate both a,b and c

Answer: 2 3/4 as an improper fraction would be B. 11/4
43 can fit into 93 two whole times.
After that, there's only room for another 7 inside the 93,
so there's no way to stuff the whole 43 in there again.
