Question

A wooden box 2m long , 65m wide and 30cm high is packed with plastic blocks 10cm long , 8cm broad and 5cm high . How many blocks are there in the box ?

Answer 1

The solution:-
2m×65m×30cm. 200×6500×30
----------------------- = ---------------------- =97500
10cm×8cm×5cm. 10×8×5

Answer 2

Wooden box
Length = 2m = 2×100 =200 cm
Width = 65m = 65×100=6500 cm
Height = 30cm
Volume of the wooden box = Lenge × Width × Height
= 200×6500×30 = 39,000,000 sq. cm

Plastic Block
Length = 10cm
Breadth / Width = 8cm
Height = 5 cm
Volume of the wooden box = Lenge × Width × Height
= 10×8×5 = 400 sq. cm

Number of plastic blocks present in wooden box =
$\frac{volume \: of \: the \: wooden \: box }{volume \: of \: the \: plastic \: block}$
$\: \: \: \: = \frac{39000000}{400} = 97500$

= 97,500 plastic blocks
