One is left to guess that the base is a rectangle. Under this assumption, the volume of water is
1/3Bh(1 - (1/2)3) = 1/3(15)(20)(10)(1 - 1/8) = 875 m3

Yes, you are subtracting the top pyramid from the bottom pyramid. The two triangles are similar so, since the dimensions of the smaller are 1/2 those of the larger pyramid, it's volume is (1/2)^3 that of the larger.

So that means we can write it this way? Volume of small pyramid= 1/3 *1/2 (20)* 1/2(15)*5 and subtract it with the Volume of the total pyramid?
