Question

A sweet box measures 20cm X 6 cm X 3cm, it is filled with sweet measuring 2x2x1 cm. How many pieces of sweets will fill the box

Answer 1

Answer:

No. of sweets = 90

Step-by-step explanation:

Here,

Volume of sweet box= 20cm × 6 cm × 3cm

= 360 cm³

And, volume of sweet = 2cm × 2cm × 1cm

= 4cm³

Now,

No. of sweets = volume of sweet box

volume of sweet

= 360cm³

4cm³

= 90

Answer 2

dimensions of the box : l1 = 20cm , b1 = 6cm , h1 = 3cm

dimensions of the sweets : l2 = 2cm , b2 = 2 , h2 = 1cm

Number of sweets required to fill the box

= ( l1 / l2 ) x ( b1 / b2 ) x ( h1 / h2)

= ( 20 / 2) x ( 6 / 2 ) x ( 3 / 1 )

= 10 x 3 x 3

= 90

method 2 :

Volume of the box

= 20 x 6 x 3

360 cm³

volume or space taken by sweets

= 2 x 2 x 1

= 4

Number of sweets required to fill the box

= Volume of the box / Volume of the sweets

= 360 / 4

= 90
