A swimming pool 9 m wide and 12 m long is 1 m deep on the shallow side and 4 m deep on the deeper side. Its volume is? Pick
A) 870m3
B) 277m3
C) 270m3
D) 220m3
E) 170m3
Volume will be length * breadth * height, but in this case two heights are given so we will take average,   Volume=(12∗9∗(1+42))m312∗9∗2.5m3=270m3   Answer: 270m3
