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

Explanation

Giventhat
Dimensions of metal block =` 2.25m xx 1.5m xx 27cm`
`=2.25m xx 1.5m xx 0.27m`
Side of each cube formed =` 45cm`
` 0.45 m `
We know that, Number of cubes can formed
`=( volume of metal block )/ (volume of one cube)`
` =(2.25×1.5×0.27) /(0.45×0.45×0.45)`
`=0.91125 / 0.091125`
` =10 cubes `
`10 cubes` are formed
