Answer 2

Answer:

28m³ is the volume of the earth that has been dug

Given:

• Length of rectangular pool = 7m
• width of rectangular pool = 4m
• height of rectangular pool = 1m

To Find:

• Volume of the pool.

Solution:

[ A rectangular hole refers to a cuboid, Whose deepth refers to the height of the cuboid ]

$\underline{\boxed{\rm volume \: of \: cuboid \: = l \times w \times h }}$

[ l = length, w = width, h = height ]

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Volume = l × w × h

Volume = 7m × 4m × 1m

Volume = 28m³

28m³ is the answer.

More to know:

The pool can not hold the same amount of water as its volume is. As a little area will be occupied by the walls of the pool. So, it will be able to holding a little less water than the volume. This measurement is called the Capacity of the pool. Capacity could be equal to or less than the volume of the container.
