W and X are two rectangular tanks. The base area of W is 88 cm
2 while that of X is 44 cm
2 . At first, W contained water to a height of 40 cm and X was empty, as shown.
- What was the volume of the water in W at first?
- Albert then poured some water from W to X. After that, the height of the water level in W was twice that in X. What was the new height of the water level in W?
(a)
Volume of water in W
= 88 x 40
= 3520 cm
3 (b)
Total base areas
= 88 + 88 + 44
= 220 cm
2 Height of water if the total base area is 220 cm
2 = 3520 ÷ 220
= 16 cm
New height of the water level in W
= 16 x 2
= 32 cm
Answer(s): (a) 3520 cm
3; (b) 32 cm
