Question

the external dimensions of a closed wooden box are 48cm,37cm,30cm. The box is made up of 1.5cm thick wood. Find it's volume​

Answer 1

Answer:

The external dimensions of a closed wooden box are 48 cm, 36 cm, 30 cm And

The box is made of 1.5 cm thick wood. So,

Internal dimension of box ( 48 - 1.5 - 1.5 = 45 cm ), ( 36 , -1.5 - 1.5 = 33 cm ) = and ( 30 - 1.5 - 1.5 = 27 cm )

So,

Volume of box = 45 x 33 x 27 = 40095

cm3

Dimension of a brick = 6 cm length , 3 cm breadth and 0.75 cm height .

So,

Volume of a brick = 6 x 3 x 0.75 = 13.5

cm3

And

Let Total number of bricks can be put in

this box = x

We can say

Volume of box = x ( Volume of brick )

So,

40095 = x (x = 40095/

So,

Total numb

box = 2970

Answer 2

Answer:volume of the box =(48−3)×(36−3)×(30−3)=38880cm cube

 

Volume of a brick=6×3×0.75=13.5cm cube

 

Number of bricks =  

13.5/38880

​  

=2970
