Question

the dimensions of a metal block are 2.25mby 1.5m by 27cm. it is melted and recast into cubes, each of side 45cm. How many cubes are formed?

Answer 1

Answer:

10 cubes

Step-by-step explanation:

2.25m=2.25*100=225cm

1.5cm=1.5*100=150cm

27cm=27cm

volume of block=225*150*27

=911,250cm²

side of cube=45cm

volume of cube=45*45*45

=91125cm²

No. of cubes formed= volume of a cube/volume of block

=911250/91125

=10 cubes
