An ice-cream brick measures 20cm by 10cm by 7cm. How many such bricks can be stored in deep fridge whose inner dimensions are 100cm by 50cm by 42cm?

Explanation

Dimension of an ice cream brick =`20cm×10cm×7cm`
Its volume =length×breadth×height=`(20×10×7) cm^3
=1400 cm^3`
Also, it is given that the inner dimension of the deep fridge is `100 cm×50 cm×42 cm`. Its volume =length×breadth× height=`(100×50×42) ``cm^3`=`210000`
bricks that can be stored in the fridge
volume of an ice cream brick /volume of the fridge = `21000/1400
=150.`
