Question
A rectangular lap pool measures 6 feet long by 4 feet wide and 2.5 feet depth. Calculate its volume.
- 100 feet3
- 60 feet3
- 150 feet3
- 180 feet3
Hint:
The pool is built inside the ground. So instead of using the word height, depth is the correct word.
The correct answer is: 60 feet3
Given:
length of pool l = 6 feet
width of pool w = 4 feet
depth of pool d = 2.5 feet
To find:
the volume of rectangular pool =?
Solution:
Let l, w, d be the length, breadth, and depth of the rectangular pool.
As the is inside the ground, the height is considered as depth.
So the pool becomes a cuboid in shape.
Suppose V is the volume of the cuboid pool.
The volume of the cuboid is given by the formula,
V = l 
b h
V = 6 42.5
V = 60 feet3
So the correct option is b.

In geometry, a cuboid is a hexahedron, a six-faced solid. Its faces are quadrilaterals. Cuboid means "like a cube", in the sense that by adjusting the length of the edges or the angles between edges and faces a cuboid can be transformed into a cube.
