Question

A cubical metal box of side 11 m has being cut and recast into cuboid of dimensions
10 cm x 11 cm x 5 cm. Find how many such cuboids can be cut out from this cube.
​

Answer 1

A cuboidal block of metal has dimensions 36 cm, 32 cm and 0.25 m. It is melted and recast into cubes with an edge of 4 cm. How many such cubes can be made?

A cuboidal block is melted & recast into cubes.

So volume is required in both figures.

Volume of a cuboid L x B x H

L =36 cm, B= 32 cm , H = 0.25 m =0 .25 * 100 = 25cm

Volume of cuboid =

36*32*25 cm^3(Substituting the values)

Volume of a cube L^3

Edge ( length ) = 4cm

= 4*4*4 cm^3

To find the number of cubes = Volume of a cuboid ÷ Volume of a cube

= (36*32*25) ÷ (4*4*4)

= 450 cubes
