From a 20cm×15cm×10cm cuboid, how many cubes of edge 5cm can be formed?

Divide each dimension by 5 and multiply the results together.

20/5 = 4

15/5 = 3

10/5 = 2

4 x 3 x 2 = 24 cubes of edge length 5 cm.

Answer 2

$Volume \: of \: Cuboid = L×B×H$

$= 8cm × 15cm × 20cm$

$= 2400 \: cm$

$L.C.M \: of \: 8,15 \: and \: 20 \: are \: 120$

$Volume \: of \: Cube \: wil \: be =l×b×h$

$=120 × 120 ×120$

$=1,728,000$

$= \frac{Volume of Cube }{Volume of Cuboid}$

$= \frac{1,728,000}{2400}$

$= 720$
