Question

the internal length,breadth,height of an open box are 95cm,75cm,and 82cm respectively.if the wood is 2.5cm thick,find the cost of painting the outside of the box at ₹ 1 per sq.dm​

Answer 1

Step-by-step explanation:

Given

Length =1m =100cm

Breath =80cm

Height =25cm

So volume of the box = lxbxh

=100x80x25 =200000cm³

Now the adding thick of wood

New length =100+2.5+2.5=105cm

New breath =80+2.5+2.5=85cm

New height=25+2.5+2.5=30cm

External volume of box after considering wood thickness =105x85x30=267750cm³

Volume of woods = 267750-200000

=67750cm³

Capacity of wooden box=200000cm³

Changing the answers in m³

200000cm³=.2m³

And wooden used =. 06775m³
