Answer:
50 cube feet of earth is removed.
Step-by-step explanation:
Given : A mason is putting in the foundation for a wall his assistant digs a trench in roughly the shape of a rectangle or solid measuring 50 feet in length 12 inches deep along both sides and 12 inches wide at the top and bottom.
To find : How many cubic feet of earth did he removed?
Solution :
The roughly shape of foundation is rectangle or cuboid.
The length is 50 feet.
The Breadth is 12 inches
We know, 1 feet = 12 inches
or 1 inches = [tex]\frac{1}{12}[/tex] feet
So, 12 inches = [tex]\frac{12}{12}=1ft.[/tex]
The height is 12 inches = 1 feet.
Now, The volume of the rectangle is
[tex]V=l\times b\times h[/tex]
[tex]V=50\times 1\times 1[/tex]
[tex]V=50 ft^3[/tex]
Therefore, 50 cube feet of earth is removed.
