Question 1124873
<br>
View the pool as a trapezoidal prism.<br>
The base of the prism is a trapezoid; the height of the trapezoid is the length of the pool (50m); the bases of the trapezoid are the depths at the two ends (1.5m and 5.5m).<br>
The height of the prism is the width of the pool (25m).<br>
The volume of the prism is (area of the trapezoidal base) times (height):<br>
The area of the trapezoidal base is (height = 50) times (average of the bases = (1.5+5.5)/2 = 3.5)<br>
Area of trapezoidal base: 50m * 3.5m = 175m^2<br>
Volume of pool: 175m^2 * 25m = 4375m^3
