Answer:
length is 4cm
width is 5cm
height is 6cm
1. To do this, multiply the length by the width by the height (L x W x H)
4x 5 x 6=120cm cubed
2. To Calculate the volume of the box .Once again we multiply L x W x H
2x 2x 2= 8cm cubed
3. Next we divide th volume
120/ 8 = 15 cubes
Therefore, it would take 15 chalks are needed to fill it if each unit calk .
