Answer:
30
Step-by-step explanation:
let EFH = x
Let GFH = y
x + y = 90
x = 2y
Substitute: 2y + y = 90
3y = 90
y = 30
11 cubic feet is the answer
The area of square is
square units
<h3><u>Solution:</u></h3>
Given that square has side length (x+5) units
To find: area of square
<em><u>The area of square is given as:</u></em>

Where "a" is the length of side
From question, length of each side "a" = x + 5 units
Substituting the value in above formula,



Thus the area of square is
square units
