Considering the volume of a rectangular prism, it is found that the depth of the pool is of 1.5 meters.
The volume of a rectangular prism of length l, width w and depth d is given by the multiplication of the dimensions, that is:
V = lwd.
For this problem, the parameters are given as follows:
V = 1800, l = 30, w = 40.
Hence the depth is found as follows:
30 x 40 x d = 1800
1200d = 1800
d = 18/12.
d = 1.5 meters.
