Dimensions of metal block,
Length, l = 4.8 m = 480cm
Breadth , b = 3.6 m = 360cm
Height, h = 2.7m = 270cm
Dimensions of cube,
Side, a = 1.8m = 180 cm
Volume of block,
Volume = l x b x h
= 480 x 360 x 270
Volume of cube,
Volume = a³
= 180 x 180 x 180
So,
No. of cubes=volume of block/Volume of cube
=480x360x270/180 x 180 x 180
= 48 x 2 x 27/18 x 1 x 18
= 24 x 1 x 27 / 9 x 9
= 8 x 27/3 x 9
= 8 x 3/3
= 8
So, the no. of cubes are 8.
Hope it may help you!!!
