Detailed Solution
Download Solution PDFGiven:
Each side of the cube = 8 cm
The rectangular container has a length of 16 cm, breadth of 8 cm, and height of 15 cm
Formula used:
The volume of cube = (Edge)3
The volume of a cuboid = Length × Breadth × Height
Calculation:
The volume of cube = The volume of the rectangular container with a length of 16 cm, breadth of 8 cm, and height of the water level rise
Let, the height of the water level will rise = x cm
So, 83 = 16 × 8 × x
⇒ 512 = 128 × x
⇒ x = 512/128 = 4
∴ The rise of water level (in cm) is 4 cm
