Solution

Dimensions of ice cream brick
$20 c m \times 10 c m \times 7 c m$
$∴$ Volume = $20 \times 10 \times 7 c m^{3} = 1400 c m^{3}$
Dimensions of inner of fridge
= $100 c m \times 50 c m \times 42 c m$
= $210000 c m^{3}$
$∴$ Number of bricks to be kept in the fridge
= $\frac{210000}{1400} = 150$
