Answer:
1040 cubic feet
Explanation:
To make it easier, you can divide the L shape into two rectangular ones. One at the left side (rectangle 1) and the other joining with it at the right (rectangle 2).
We know the volume of a rectangle is
V = L x W x H
where L = length
W = width
H = height
So for rectangle 1:
length = 10 ft
width = 20 - 16 = 4 ft
height = 10 ft
Volume (rectangle 1) = 10 x 4 x 10 = 400 cubic feet
and for rectangle 2:
length = 16 ft
width = 10 - 6 = 4 ft
height = 10 ft
Volume (rectangle 2) = 16 x 4 x 10 = 640 cubic feet
We will add the volumes of both the shapes to get the volume of the pool:
Volume of pool = 400 + 640 = 1040 cubic feet
