A rectangular swimming pool is 8.0 m long. Each cubic metre of water added to the pool increases the depth by 32 mm.
Volume of water 1 cu.m
length of pool = 8.0 m
height per cu.m of water = 0.032 m
Volume = L * W * h
1 = 8* w * 0.032
w= 1/(8*032)
width of the pool = 1.9 m

(b) How much water is needed to fill the pool to a depth of 2.3 m?
Round to the nearest whole.
V = L * W * h
V= 8* 1.9 *2.3
34.96 ~ 35m^3
