Question

the dimensions of a metal block are 2.25 m by 1.5 m by 27 cm It is melted and recast into cubes each of side 45 cm how many cubes are formed

Answer 1

No. of cubes= volume of metal block\volume of cube
=l×b×h\(a)cube
=225×150×27\45×45×45
=10 cubes
No. of cubes are 10

Answer 2

Hi ,

Dimensions of the metal block ,

Length = l = 2.25 m = 225 cm

Breadth = b = 150 cm

Height = h = 27 cm

Each side of the cube = a = 45 cm

If block is melted and cast into

Cubes

Let number of cubes = n

n = volume of block / volume of a cube

= ( lbh ) /a³

= ( 225 × 150 ×27 )/ ( 45 )³

= 10

Number of cubes formed = n = 10

I hope this helps you.
