Solution
\[\text { Dimension of an ice cream brick = 20 cm } \times 10 cm \times 7 cm\]
\[\text { Its volume = length } \times \text { breadth } \times\text { height } = (20 \times 10 \times 7) {cm}^3 = 1400 {cm}^3 \]
\[\text { Also, it is given that the inner dimension of the deep fridge is 100 cm } \times 50 cm \times 42 cm . \]
\[\text { Its volume = length } \times\text { breadth } \times \text { height } = (100 \times 50 \times 42) {cm}^3 = 210000 {cm}^3 \]
\[ \therefore \text { The number of ice cream bricks that can be stored in the fridge }= \frac{\text { volume of the fridge }}{\text { volume of an ice cream brick }} = \frac{210000 {cm}^3}{1400 {cm}^3} = 150\]
