A container measuring 17cm by 8cm by 10cm was half filled with water. When 8 cubes were put in, the water level became 8cm. Find the volume of each cube.
Solution
Height increase -----
8 cm (new height) – 5 cm (half tank) = 3 cm
Volume of 8 cubes -----
17cm x 8cm x 3cm
= 408 cubic cm
1 cube ----- 408 cubic cm divided by 8
= 51 cubic cm
Answer: 51 cubic cm
