Question 1.
A large fish pond is 5 meters long, 4 meters wide, and 12 centimeters deep. What is the volume of the pond in centimeters?
2,400.000 cm3

Question 2.
A rectangular pool has a base area of 600 ft2. The total volume of the pool is 4,800 ft3. How deep is the pool?
Given rectangular pool,
Area of base (b) = 600 ft2
Total volume of the pool (v) = 4,800 ft3
Deep of the pool (h)= ?
v = b x h
4,800 ft3 = 600 ft2 x h
4,800 ft3/600 ft2 = h
8 feet = h
The pool is 8 feet deep.

Area of the rectangular floor (A)= 24 square meters
Length of the room (l) = 6 meters
Width of the room (w) = ?
A = l x w
24 m2 = 6 m x w
24 m2 /6 m= w
4 m = w
Width of the room is 4 meters.
