V and W are two rectangular tanks. The base area of V is 94 cm
2 while that of W is 48 cm
2 . At first, V contained water to a height of 33 cm and W was empty, as shown.
- What was the volume of the water in V at first?
- Vaidev then poured some water from V to W. After that, the height of the water level in V was thrice that in W. What was the new height of the water level in V?
(a)
Volume of water in V
= 94 x 33
= 3102 cm
3 (b)
Total base areas
= 94 x 3 + 48
= 330 cm
2 Height of water if the total base area is 330 cm
2 = 3102 ÷ 330
= 9.4 cm
New height of the water level in V
= 9.4 x 3
= 28.2 cm
Answer(s): (a) 3102 cm
3; (b) 28.2 cm
