Question

A cuboid of dimension 8*4*7 is to ne divided into identical cubes of 1*1*1 dimension each then find the no. Of long straight cuts needed if the cube or any of its part cannot be moved

Answer 1

Given:

A cuboid of dimension 8, 4 and 7.

To find:

Number of cut needed to make cube.

Solution:

1) To obtain the cube we need the unit length from all side so we cut the cuboid from length 7 times of unit distance.

2) we cut the cuboid from the breadth in 3 parts of unit length.

3) From the height of the cuboid we cut it into 6 parts.

Number of cuts needed to make cube 7+3+6 = 16 cuts.
