The dimensions of an ice compartment in a refrigerator 8 cm × 5 cm × 4 cm. How many ice cubes will it hold, if each ice cube is 2 cm on its edge?

Correct option is C

Given:

Dimensions of the ice compartment: 8 cm×5 cm×4 cm

Each ice cube is a cube with an edge of 2 cm

Formula Used:

​$$\text{Number of ice cubes} = \frac{\text{Volume of ice compartment}}{\text{Volume of one ice cube}}$$​​

Volume of cuboid = Length × Breadth × Height

Solution:
Volume of ice compartment:

​$$8 \times 5 \times 4 = 160 \text{ cm}^3$$​​

Volume of one ice cube:

​$$2 \times 2 \times 2 = 8 \text{ cm}^3$$​​

Number of ice cubes:

​$$\frac{160}{8} = 20$$

Option (C) is right.
