Tank a which measured 20 cm by 14 cm by 16 cm was empty. tank b with a base area of 200 cm2 and a height of 35 cm was completely filled with water the water from tank b was then poured into tank a to its brim

(a) what was the volume of water in tank b at first

(b) what was the volume of water in tank b at the end

a) 4480cm³

              b)2520cm³

Step-by-step explanation:

a) Volume of tank B:

V=B*c

B=200cm²

c=35cm

Vb=200*35

Vb=7000 cm³

b) Volume of water in tank B on the end(Vend) is claculated like:

Fiirst we find volume of tank Va(that is how much water was pured out of tank B), than  Vb-Va to get volume of water in tank B at the end

Va=abc

a=20cm

b=14cm

c=16cm

Va=20*14*16

Va=4480cm³

Vend=Vb-Va

Vend=7000cm³-4480cm³

Vend=2520cm³
