John is digging a hole for a swimming pool,the hole will be 28 feet long, 5 feet wide, 34 feet wide. How much cubic feet of dirt

ivann1987 [24]

Answer:

John need to remove 4760 cubic feet of dirt.

Step-by-step explanation:

Given:

John is digging a hole for a swimming pool,the hole will be 28 feet long, 5 feet wide, 34 feet wide.

Now, to find the cubic feet of dirt John need to remove.

Length = 28 feet.

Width = 5 feet.

Height = 34 feet.

As the swimming pool is in the shape of a rectangular prism.

So, we put formula of volume to get the cubic feet of dirt need to remove:

$Volume = length\times width\times height$

$Volume=28\times 5\times 34$

$Volume=4760\ cubic\ feet.$

Therefore, John need to remove 4760 cubic feet of dirt.
