and deep
ends

amount of water in litres required to fill the
pool
Answers
Answer:
1350000 litres of water
Step-by-step explanation:
volume of rectangular prism + volume of triangular prism gives you the total volume in cu.m.
900 + 450 = 1350 cu.m
1 cu.m =1000 litres of water
Answer:
1350000 litres.
Step-by-step explanation:
The cross section of the swimming pool is a trapezium with parallel sides 1.5m and 3m (depth of both ends) and 40m (length of pool) as the ⊥ r distance between ∥ sides.
The width of pool 1.5m can be the length of cross section.
Length of swimming pool = 40m
Breadth of the pool = 15m
Depth of the pool = 1.5m and 3m
∴ Volume of the water = 1 /2 [(1.5+3) x 40] x 15m3
= 1/2 x 4.5 x 40 xt 15m3
=1350 m.
Capacity of water in litres =1350 × 1000 litres
(1m3 =1000litres)
=1350000 litres .
