A and B are two rectangular containers. The base area of A is 92 cm
2 while that of B is 46 cm
2 . At first, A contained water to a height of 48 cm and B was empty, as shown.
- What was the volume of the water in A at first?
- Jack then poured some water from A to B. After that, the height of the water level in A was twice that in B. What was the new height of the water level in A?
(a)
Volume of water in A
= 92 x 48
= 4416 cm
3 (b)
Total base areas
= 92 + 92 + 46
= 230 cm
2 Height of water if the total base area is 230 cm
2 = 4416 ÷ 230
= 19.2 cm
New height of the water level in A
= 19.2 x 2
= 38.4 cm
Answer(s): (a) 4416 cm
3; (b) 38.4 cm
