Question

When a cuboid of dimensions 30cm×30cm×42.6cm is melted and converted into cubes of edge 3 cm, then the number of cubes formed is​

Answer 1

Answer:

volume of cuboid is 38340

volume of cube is 27

38340÷27=1420

no of cubes formed =1420

Answer 2

Step-by-step explanation:

Given :-

dimensions of the cuboid :-

length = 30cm

breadth = 30cm

height = 42.6cm

dimensions of the cube :-

side = 3cm

ATQ, the solid cuboid of the given dimensions is melted and converted into small cubes of side 3cm.

we've to find the no. of cubes formed.

for that we needa divided the volume of cuboid by the volume of the cube.

hence, the no.s of cube formed = (30 × 30 × 42.5)/(3 × 3 × 3)

= (10 × 10 × 42.5)/3

= 4250/3

= 1416.6 approximately

hence, 1416 full cubes can be formed from the cuboid.
