An ice-cream brick measures 20 cm by 10 cm by 7 cm. How many such bricks can be stored in deep fridge whose inner dimensions are 100 cm by 50 cm by 42 cm?
Answer:
Given details are,
Dimensions of ice cream brick = 20 cm × 10cm × 7cm
Dimensions of fridge is = 100 cm × 50cm × 42 cm
So,
Number of bricks that can be put in fridge = volume of fridge / volume of one ice brick
= (100 × 50 × 42) / (20 × 10 × 7)
= 150 ice cream bricks
