Question

How many cubes of side 5 cm can be packed in a box of 30 cm x 25 cm x 20 cm?

Answer 1

Volume of a cuboid = l x b x h = 30 $\times$ 25 $\times$ 20= 15000 cu cm
Volume of a cube =l x b x h =5$\times$5$\times$5= 125 cu m
Number of cubes that can be packed in a box $\frac{15000}{125}$= 120 cubes
