Answer:
5ft
Step-by-step explanation:
Given parameters:
Length of the pool = 25ft
Width of the pool = 15ft
Volume of water the pool can hold = 1875ft³ of water
Unknown:
Depth of the pool = ?
Solution:
The pool is in the shape of a cuboid.
The volume of a cuboid is given as;
Volume of a cuboid = L x width x depth
Insert the parameters and solve for the depth;
1875 = 25 x 15 x depth
depth = = 5ft
