+130544 The volume of water in Tank A = (3/4)(12)(25)(20) = 4500cm^3
And the base area of Tank A -= 12 * 25 = 300 cm^3
And since the base area of Tank B is twice that of Tank A, its capacity is (600)cm^3
And we want to know this :
300h + 600h = 4500 where h is the equal height of water in both tanks
900h = 4500 divide by 800 on both sides
h = 5cm
