Required volume = Volume of triangular wedge + volume of cuboid
for volume of wedge= Area of triangle x 20(width of pool)
area of triangle= 1/2 x b xh
here b= 48 m
now we have to calculate only h
given: Slope(m)=tan θ
for tan θ, first find sin θ=10/2.6=5/13
therefore tan θ=5/12
now for big triangle, tan θ= h/48
thus h=20
Now do the rest of the calculation to get the result
