G and H are two rectangular tanks. The base area of G is 77 cm
2 while that of H is 33 cm
2 . At first, G contained water to a height of 34 cm and H was empty, as shown.
- What was the volume of the water in G at first?
- Fabian then poured some water from G to H. After that, the height of the water level in G was twice that in H. What was the new height of the water level in G?
(a)
Volume of water in G
= 77 x 34
= 2618 cm
3 (b)
Total base areas
= 77 + 77 + 33
= 187 cm
2 Height of water if the total base area is 187 cm
2 = 2618 ÷ 187
= 14 cm
New height of the water level in G
= 14 x 2
= 28 cm
Answer(s): (a) 2618 cm
3; (b) 28 cm
