Answer:
<h2>108 yd²</h2>
Step-by-step explanation:
The formula of an area of a trapezoid:

<em>b₁, b₂</em><em> - bases</em>
<em>h</em><em> - height</em>
From the picture we have

Substitute:

From the information given;
1 bag of concrete = 1000 in^3
2 bags at home = 1000*2 = 2000 in^3
The available space has a volume of;
Volume = (5*12)*10*10 (Note: 1 ft = 12 inches)
Volume = 60*10*10 = 6000 in^3
The remaining volume = Available space - occupied space = 6000 - 2000 = 4000 in^2
1 bag = 1000 in^3
x bags = 4000 in^2
Then,
x = 1*4000/1000 = 4 bags.
This means 4 more bags of concrete will be required to fully fill the space.
