Question

The dimensions of a box are $50cm\times 36cm\times 25cm$ how much ${cm}^2$cloth will be required for making cover of the box?

Answer 1

$50cm\times 36cm\times 25cm$

Size of both required will be different while compared to size of box because we need extra cloth around edges. It may be $5cm$ extra.

So are of cloth is $55cm\times 41cm\times 30cm$ that is $2(55\times 41)+2(41\times 30)+2(30\times 55)$

$=4510+2460+3300=$

$=10270sq.cm$
