Question

Varsha makes a cuboid of plasticine of sides 8 cm, 10 cm, 15 cm. How many such cuboids will be needed to form a cube?

Answer 1

Step-by-step explanation:

first we will find the volume of cuboid

= L * B * H

= 8*10*15

= 1200cm³

now find the L.c.m of these dimensions=

8,10,15

=120

Each side of the cube will be having a length of 120 cm

now calculate the volume of cube

= side * side * side

120*120*120

1728000cm³

Number of cubes will be = 1728000cm³/ 1200 cm³

=1440
