The external dimensions of a closed wooden box are 48 cm, 36 cm, 30 cm. The box is made of 1.5 cm thick wood. How many bricks of size 6 cm x 3 cm x 0.75 cm can be put in this box?
Given internal dimensions are
∴ Internal volume =`45xx33xx27cm^3`
Volume of brick = `5xx3xx0.75cm^3`
Hence, number of bricks= `"Internal volume"/"volume of 1 brick"`
`∴2970 "bricks can be kept inside the box"`
