Answer 1

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 = $\frac{1}{12}$ feet

So, 12 inches = $\frac{12}{12}=1ft.$

The height is 12 inches = 1 feet.

Now, The volume of the rectangle is

$V=l\times b\times h$

$V=50\times 1\times 1$

$V=50 ft^3$

Therefore, 50 cube feet of earth is removed.

Answer 2

V = LWH 

V = 50 * 1 * 1 is the answer
