Question

How many cubes of 2 cm are needed to build a cuboid measuring 6cm by 8cm by 4cm?​

Answer 1

$➪ VOLUME \: \: OF \: \: CUBOID =\: \:6 \times 8 \times 4 = 192$

$➪ VOLUME \: \: OF \: \: CUBOID = \\ {2}^{2} = 8 \: {cm}^{2}$

➪ so,no of cubes that can cut off cuboid ..

$➪ cuboid = \frac{192}{8} = 24$

Answer 2

Answer:

24 cubes

Step-by-step explanation:

1. The volume will remain the same when changing the n cubes to

a cuboid of 6*8*4 cm^3

2. Volume of the cube=2*2*2=8cm^3

3. Volume of the cuboid =6*8*4=192cm^3

IF n number of cubes are needed to make one cuboid then

192=n*8

>> This mean 192/8=24 cubes of 2cm are needed to build a cuboid of

6*8*4 cm^3
