C and D are two rectangular containers. The base area of C is 92 cm
2 while that of D is 46 cm
2 . At first, C contained water to a height of 34 cm and D was empty, as shown.
- What was the volume of the water in C at first?
- Bryan then poured some water from C to D. After that, the height of the water level in C was twice that in D. What was the new height of the water level in C?
(a)
Volume of water in C
= 92 x 34
= 3128 cm
3 (b)
Total base areas
= 92 + 92 + 46
= 230 cm
2 Height of water if the total base area is 230 cm
2 = 3128 ÷ 230
= 13.6 cm
New height of the water level in C
= 13.6 x 2
= 27.2 cm
Answer(s): (a) 3128 cm
3; (b) 27.2 cm
