2 while that of B is 31 cm
2 . At first, A contained water to a height of 58 cm and B was empty, as shown.
- What was the volume of the water in A at first?
- Oliver then poured some water from A to B. After that, the height of the water level in A was thrice that in B. What was the new height of the water level in A?
(a)
Volume of water in A
= 73 x 58
= 4234 cm
3 (b)
Total base areas
= 73 x 3 + 31
= 250 cm
2 Height of water if the total base area is 250 cm
2 = 4234 ÷ 250
= 16.936 cm
New height of the water level in A
= 16.936 x 3
= 50.808 cm
Answer(s): (a) 4234 cm
